To activate the system, press the DCA (Distance Control Assist) switch once on the lower right side of the steering wheel. A white little car icon in the top center of the instrument cluster will display as you are approaching another vehicle to let you know that the radar has detected it and will begin applying the brakes as you get closer. Additionally, it is activated by adaptive cruise control. Although it is a fantastic function and will stop your automobile, be ready to brake at all times. The brakes will be applied for a few seconds after the vehicle comes to a halt, then they will release (you will hear a beep). Use your foot brake because, more often than not, if you get too close to the car in front of you after it has stopped, the radar won’t be able to detect it.
I frequently utilize the system and do have faith in it, but I am always ready to depress the brake just in case. The ECO setting in the transmission helps prevent overexcellerating by having the gas pedal push back slightly against your foot while I’m in bumper-to-bumper traffic. drives more smoothly as a result. I hope this clarifies your query.
Distance Control Assist in the INFINITI Q60
When the dynamic driver assistance switch on the steering wheel is pushed, the Distance Control Assist system activates if it is activated in the options menu. The DCA system switch indicator will become visible in the vehicle information display once it is turned on. To turn off the DCA system, press the dynamic driver assistance switch once more. A DCA system indication will stop flashing. Please be aware that when the standard cruise control mode is in operation, the DCA system does not function. Additionally, it’s possible that a car entering the lane in front of it won’t be seen until it’s moved all the way in. A chime will play and the system indicator will blink if this happens.
In the lower display, the DCA can be enabled or disabled. To turn on or off the DCA:
- Activate the MENU button.
- On the lower display, press the DRIVER ASSISTANCE key.
- On the lower display, press the FORWARD ASSIST key.
- Toggle the system ON or OFF by pressing the DISTANCE CONTROL ASSIST key.
The following indicators will appear on the DCA system’s display:
- The DCA system is activated when a green indicator turns on.
- If there is a problem, an orange signal turns on.
- The vehicle information display will display this indicator if there isn’t a car in front of you in your current moving lane.
- The vehicle information display will display this indicator if a car is in your travel lane ahead of you.

What does DCA in a car stand for?
The rate (power) that the battery will accept during charging is known as dynamic charge-acceptance (DCA). According to Section 5.2 of Chapter 5, the adoption of “stop-start” operation is the first step in the gradual improvement of vehicle fuel economy. This raises the demands placed on the battery significantly. The battery was previously charged by a distinct alternator and only needed to power one engine start event every trip (up to about 6 kW for a short period of time for a medium-sized automobile), together with lighting, ignition, and other electrical loads (to a maximum of 2 kW continuously). When the stop-start system is in use, the average trip will need multiple engine restarts, with each one requiring roughly 7 Wh for a car with a traditional starter and alternator but only about 1 Wh for one with an integrated starter-generator (ISG). More crucially, during engine-off periods, the battery must be the only source of power for the sum of all continuous demands. Batteries in stop-start automobiles will consequently undergo a deeper discharge than those in earlier vehicles. Additionally, because the internal combustion engine’s (ICE) output alone must be used to replenish the additional charge that is extracted, the battery may spend a sizable portion of its time in an unfavorably low state of charge. Regenerative braking, which is the capture of energy in the form of electricity that would otherwise be lost as friction during braking but is only available for a few seconds and at very high rates, can help vehicles shorten this period. Dynamic charge-acceptance (DCA), which refers to how a battery can take charge that comes from kinetic energy recovery as opposed to other modes of charging, is a crucial metric in this case.
An ISG, as opposed to a separate starter and alternator, is typically built inside a car that is intended to use regenerative braking energy. The battery’s ability to accept charges limits the amount of energy that can be absorbed with currents of 100 to 200 A. The battery voltage has a big impact on this. Tens of kW are allowed in hybrid electric vehicles with high-voltage battery packs, while only roughly 1 kW is allowed in 12-V batteries. The two types of battery have very different configurations, despite the fact that the total energy stored in full hybrids and 12-V stop-start hybrid vehicles (SSVs) is roughly equal ( 1 kWh; see Table 5.1, Chapter 5). During DCA, the HEV battery’s cells ( 6 Ah) are subjected to charge rates of 30 C1 or higher, whereas the SSV battery’s cells (up to 100 Ah) are only subjected to rates of 1 to 2 C1.
The percentage of available braking energy that can be recovered will increase in proportion to the battery’s DCA. The quantity of current that the charge reaction can accommodate without wasting is a measurement of the process’s efficacy. Lead-acid batteries’ ability to accept a charge at the high currents generated by regenerative braking poses a major challenge; for more information, see Section 5.2.1 of Chapter 5. In the case of lead-acid batteries, the amount of energy recovered is somewhat dependent on the battery’s recent history (i.e., whether it was charged, discharged, or rested). An efficient method of maintaining DCA seems to be a system that periodically fully charges the battery, although this is not a quick fix.
Describe the DCA battery test.
Dynamic Charge Acceptance (DCA) of a cell is a measurement of the battery’s or cell’s capacity in relation to the capacity of the battery’s ability to absorb electrical charge.
In the case of electric and hybrid electric vehicles, where the battery’s capacity to take energy dictates the amount of energy that can be recovered from the vehicle as it slows down, this characteristic is very crucial. Battery chemistry, battery temperature, state of charge (SoC), and usage history of the battery or cell can all affect the DCA.
All testing has been done in temperature-controlled environments, with the cells placed in free air within temperature-controlled chambers. This kind of testing has the advantage of allowing testing to be done below 0 0C while still maintaining uniformity throughout the test procedure.
Testing has been done at -10, 0, 10, 25, and 40 degrees Celsius. This temperature range encompasses the typical range of temperatures that could be anticipated to occur in real-world use within EVs.
DCA tests have been performed on the cells using an advanced battery and cell testing system at different SoC and charge histories, specifically: 10, 30, 50, 70, & 90% SoC with a charge history, and 90, 70, 30 & 10% SoC with a discharge history for the battery / cell.
Numerous chemistries, including improved Lead-based cells and lithium-based cells, have been tested to ascertain their features. To enable like-to-like comparisons, the test results are scaled to the cell capacity “C.”
In the figures, a representative result from a lithium iron phosphate cell (PLS-007) and an advanced lead based cell (B02/06-49) are displayed for comparison.
These display the behavior of the cells for each of the 20 energy pulses that are sent back into them at 25 oC, at different levels of charge, and for the cell’s prior charge and discharge history.
By restricting the current in each scenario to 4 times the cell’s “C” rate, the maximum value of the energy was mitigated. It is interesting to note from the results that, for some applications, choosing between lithium-based batteries and lead-based batteries may not be an easy decision.
