Pre-Collision System (PCS), one of the components in the Toyota Safety Sense family of driver-assistive technologies, is a standard feature on many Toyota automobiles. In certain circumstances, the technology uses a forward-facing radar and camera to scan the road ahead to assist drivers in avoiding a potential frontal accident. For an overview of PCS’s operation, check this video.

Toyota PCS Warning Light Definition
Warning signal/information: Light from the Pre-Collision System shows that the Pre-Collision System is broken. When the system is in use, the light will flash rapidly. As soon as the Pre-Collision System is turned off, the light will come on.
Describe the Toyota PCS system.
The Pre-Accident Safety (PCS) system has been created to warn you when a frontal collision is likely[S1][J11] using the built-in camera or radar in your car.
To assist you in avoiding collisions or lessening their severity, some recent models even come equipped with PCS with Pedestrian Detection (which, depending on your vehicle, may be effective during the day and/or at night)[S1][J11] and PCS with Cyclist Detection (effective only during the day).
My pre-collision light turned on, why?
The pre-collision sensor employs radar to determine whether a collision is about to occur when the automobile is in drive and approaching another vehicle or object. The pre collision system will activate if a collision is detected, which can help to lessen the impact of the collision or possibly prevent it completely.
The majority of pre-collision devices operate automatically, and most collisions are unforeseeable. A pre collision system uses highly developed technology. Pre-collision systems are not flawless, but by lowering the frequency of accidents, they can help make the roads safer for everyone.
Ask your dealership or an automotive repair provider for more information if you’re curious about pre-collision systems or other driving aids. They will be able to provide you with further information about these systems’ functionality and whether they are offered on the cars you are considering.
My collision light turned on, why?
By identifying stationary or slowly moving cars in front of your car, forward collision warning systems alert you to the possibility of an impending collision. While you are driving, forward collision warning uses radar, lasers, or cameras to monitor the road ahead. The technology will alert you to the danger if there is an oncoming collision utilizing lights, beeps, seat vibrations, or a combination of these. Additionally, certain systems might tighten your seatbelt and pre-charge your brakes to help you stop as swiftly as possible.
Forward collision warning systems are rapidly being included into a large number of automobiles, along with other safety features like automated emergency braking. If you don’t apply the brakes quickly enough to avoid an approaching collision, your car will do it for you if it has automated emergency braking. Even though autonomous emergency braking might not stop every collision, the technology might assist reduce the severity of one.
Activation/Deactivation
At speeds greater than 10 mph, the majority of forward collision warning systems are automatically activated. By pushing the forward collision warning system button or by gaining access to your forward collision warning settings via your vehicle’s information screen, you can deactivate the system. For information relevant to your vehicle, consult your owner’s manual.
What you should do
Always keep a safe distance between you and the car in front of you. Your forward collision warning system is designed to alert you if you approach the car in front of you too closely. Be ready to brake or steer to safety if your forward collision warning system issues a warning or starts to slow down for you.
How Does it Work?
sensors for distance and speed. In order to keep you safe, forward collision warning systems use both speed and distance estimates. Although radar is the most popular type of distance sensor, some systems utilize lasers, cameras, or a mix of these to detect traffic in front of you. These sensors identify stationary or slow-moving cars in your lane and alert you if an accident is imminent.
A closer look at radar-based systems Let’s examine the operation of forward collision warning systems based on radar. Some radar waves sent by forward collision warning systems are reflected back from objects in front of your car. Forward Collision Warning analyzes your speed and the varying distance to the vehicle in front of you to determine whether a collision is about to occur based on the radar reflection.
Emergency braking on command. Some technologies that warn of impending collisions function in tandem with automatic emergency braking. If your car has automatic emergency braking, the system will apply the brakes quickly when a collision is about to happen if you don’t do it in time.
How quickly does the Toyota pre-collision system function?
The Toyota Pre-Collision system concentrates on this area since it is believed that more than 90% of rear-end collisions occur when the difference in speed is less than 38 mph. Unavoidable crashes are more likely to occur with less severity when this system is in operation.
What functions does Toyota’s pre-collision assist?
A front-facing camera and laser are used by the Toyota Pre-Collision System to identify obstacles in your path and signal when it is time to apply the brakes. It can even stop your car completely automatically if necessary.
What function does a pre-collision avoidance system serve?
Applications that deal with driving safety mostly refer to cooperative collision avoidance systems (CCAS) [22], which expand collision avoidance systems (CAS) by exchanging CAS information with other vehicles, typically via V2V communication [23,24].
CAS, sometimes referred to as precrash system, forward collision warning system, or collision mitigation system, detects an impending collision using radar or other sensors (such as laser and camera) and either warns the driver or immediately applies the brakes or adjusts the steering. As seen in Fig. 16.6, CCAS encourages vehicle cooperation to reduce collisions between many vehicles.
How does pre-collision assistance function?
Ford may produce modern cars with a feature called Pre-Collision Assist with Automatic Emergency Braking. Pre-Collision Assist employs camera technology to identify probable collisions with oncoming traffic or pedestrians. When a potential collision is identified, the vehicle’s messaging center flashes a warning message and emits an alarm sound. The AEB will be pre-charged and the brake-assist sensitivity will be raised if the driver’s response is insufficient to ensure full responsiveness in the event that the driver brakes. The vehicle’s brakes can automatically engage if there is no apparent corrective action and a collision is about to happen. Some crashes can be avoided, and the severity of others can be lessened, by spotting the potential collision and activating the braking system.
The 2020 Ford Explorer was used to test this system. The instrumented Ford was driven at a dummy target car or person over many tests. The range at which the system activated, the closing speeds at which it avoided a collision, the rate at which the car decelerated after the system triggered, and the behavior of the system when the driver intervened were all investigated.
How does my Toyota understand the posted speed limit?
Road Sign Assist (RSA), which employs an intelligent camera, is made to recognize yield signs, stop signs, do not enter signs, and speed limit signs. The system updates the Multi-Information Display with the signs.
Feature accessibility varies depending on the car and/or trim level. Available on vehicles equipped with TSS 2.0, TSS 2.5, and TSS 2.5+.
Can the Toyota Highlander brake automatically?
The Highlander’s camera-radar system works to warn you when there are vehicles nearby when you are parking, both visually and audibly. When the driver does not immediately respond to the signals, it is meant to automatically deploy the brakes in conjunction with the Intelligent Clearance Sonar and Rear Cross-Traffic Braking.
Toyota Safety SenseTM 2.5+
In order to help you operate the Highlander within acceptable safety margins, Toyota has developed this suite of safety technologies with support functions. This system has attributes like:
- Road Sign Support
- Auxiliary High Beams
- Pre-Collision System with Pedestrian Detection in Low Light
- Support for Lane Tracing
- a dynamic radar cruise control with a full speed range
- Alert for lane departure with steering assistance
What does PCS in a car mean?
Early Collision System PCS makes use of a camera and laser radar to find objects in front of the car. The technology warns the driver to brake with an auditory and visual alarm when it decides there is a chance of a collision. The device applies more braking pressure if the driver detects the hazard and brakes.
My collision mitigation system has to be reset.
While driving, the forward emergency braking (FEB) and adaptive cruise control systems disable themselves at random. This creates a significant problem when operating the vehicle. When this occurs, the car is moving. The only way to reset the system is to stop the vehicle, turn off the ignition, and then restart the engine. The Collision Mitigation Braking System activated while traveling at 50 mph, causing the vehicle to abruptly brake. The car was transported to [a Honda dealership] for a diagnosis, but the problem’s root cause was unable to be found. The issue persisted because the car was not repaired. The problem was communicated to the manufacturer […] The mileage of failure was 28,000.
The car sensed a car in the right lane as it was moving at 70+ miles per hour along the interstate and automatically applied the brakes, reducing the speed to 55 or less. However, there were open lanes and no danger of a collision. The braking nearly caused me to be rear-ended. Additionally, the car’s sensors have frequently activated for collision alerts when I am turning left at a stoplight or driving through a metropolis with no other vehicles in sight. It is necessary to fix this since it is unsafe.
Will the car be stopped by Toyota Safety Sense?
If you don’t have active safety controls in place, there aren’t many methods to prevent the accident that occurs when a stray dog darts out in front of you just as you sneeze. The pre-collision technology uses cameras and lasers to detect activity in front of you and provide visual and audible alerts. The system won’t take any more action if the driver responds in time. However, Toyota Safety Sense employs the sensors to automatically apply the brakes to stop the vehicle if the driver is otherwise unable to do so. While PCS cannot completely eliminate the possibility of an accident, it can considerably lower your speed in order to either avoid or decrease the consequences of a collision.
