摘要： A yaw stability control system (18) is enhanced to include roll stability control function for an automotive vehicle and includes a plurality of sensors (28-39) sensing the dynamic conditions of the vehicle. The sensors may include a speed sensor (20), a lateral acceleration sensor (32), a yaw rate sensor (28) and a longitudinal acceleration sensor (36). The controller (26) is coupled to the speed sensor (20), the lateral acceleration sensor (32), the yaw rate sensor (28) and a longitudinal acceleration sensor (36). The controller (26) generates both a yaw stability feedback control signal and a roll stability feedback control signal. The priority of achieving yaw stability control or roll stability control is determined through priority determination logic. If a potential rollover event is detected, the roll stability control will take the priority. The controller for roll stability control function determines a roll angle of the vehicle from the lateral acceleration sensor signal and calculates the feedback control signal based on the roll angle.

摘要： A method for preventing a valve orifice from switching to the small size when a high build gradient is required includes briefly bleeding off a small amount of fluid at the upstream side of the valve. This momentarily reduces the pressure difference when beginning the pressure build. After the valve is opened with the large orifice, the fluid flow through the valve prevents a high pressure difference. The resulting build with the large orifice has the maximum pressure gradient.

摘要： The method for controlling a safety system (102-108) of a vehicle (10) determines a reference velocity from a first front wheel sensor (20A) and a second front wheel speed signal from a second front wheel sensor (20B). An axle speed sensor (20C) may be used to determine an axle speed signal. A first rear speed signal and a second rear speed signal are determined from the reference velocity, a slip effect and a yaw signal. The yaw signal may be determined from a yaw rate sensor (28). Safety system (102-108) may be controlled in response to the first rear wheel speed signal and the second rear wheel speed signal.

摘要： A system for maintaining hydraulic pressure in a vehicle hydraulic system when the vehicle is stopped or idling. A hydraulic pressure reserve system includes a primary hydraulic circuit that includes a hydraulic pump and a hydraulic sump and that provides hydraulic pressure to at least a hydraulically actuated transmission and an accumulator tank and control valve connected from the primary hydraulic circuit for storing a reserve of hydraulic fluid at an accumulator pressure. An accumulator control valve, such as a bi-directional valve, allows a flow of hydraulic fluid between the primary circuit and the accumulator tank according to the primary circuit pressure to raise the primary circuit pressure towards a desired pressure. The hydraulic pressure reserve system may include a primary gear connected from a primary drive and driving an auxiliary secondary gear with a primary drive clutch for connecting the secondary gear to drive the hydraulic pump and an auxiliary drive clutch for connecting the auxiliary secondary gear or a drive chain to drive the hydraulic pump.

摘要： A stability control system (24) for an automotive vehicle as includes a plurality of sensors (28-37) sensing the dynamic conditions of the vehicle and a controller (26) that controls a distributed brake pressure to reduce a tire moment so the net moment of the vehicle is counter to the roll direction. The sensors include a speed sensor (30), a lateral acceleration sensor (32), a roll rate sensor (34), and a yaw rate sensor (20). The controller (26) is coupled to the speed sensor (30), the lateral acceleration sensor (32), the roll rate sensor (34), the yaw rate sensor (28). The controller (26) determines a roll angle estimate in response to lateral acceleration, roll rate, vehicle speed, and yaw rate. The controller (26) changes a tire force vector using brake pressure distribution in response to the relative roll angle estimate.
