Roll stability control system |
摘要 |
A roll stability control system for a pneumatically operated vehicle brake system is implemented using simpler ABS hardware rather than more complex EBS hardware. For each brake chamber or channel, two 3/2 solenoid controlled valves are used. An ECU is operative to control the solenoids. The ECU is preferably operative to provide a selected delivery pressure to the brake chamber without measurement of delivery pressure to the brake chamber. Supply air is provided at a known pressure to a first solenoid controlled valve that is associated with the brake chamber; the amount of time of energization and de-energization of the first valve that is needed to provide an output therefrom of a given pressure, is calculated; and the first valve is energized and de-energized for the calculated times, thereby to cause a low-pressure test pulse to be provided to the brake chamber.
