摘要： An electrohydraulic brake system where brake pressure is controlled by the combined action of an apply valve and a dump valve by the implementation of a method of controlling the voltage applied to the apply and dump valve. The EHB pressure control system receives a desired wheel pressure command and, with a caliper pressure feedback signal, implements an algorithm to compute one voltage command for the apply valve and another for the dump valve. The solenoids of the proportional apply and dump poppet valves are operated to control flow in or out of the brakes and modulate wheel pressure as required. The algorithm is used to control the electromagnetic poppet valves in all states of flow through the valve. The algorithm is a function of the existing pressure within the system and whether there is bulk or leakage flow through the valves.

摘要： An electrohydraulic brake system where brake pressure is controlled by the combined action of an apply valve and a dump valve by the implementation of a method of controlling the voltage applied to the apply and dump valve. The EHB pressure control system receives a desired wheel pressure command and, with a caliper pressure feedback signal, implements an algorithm to compute one voltage command for the apply valve and another for the dump valve, corresponding to a requested flow from the hydraulics. The voltage command drives current control electronics. The electronics in turn power the solenoids of the proportional apply and dump poppet valves to control flow in or out of the brakes and modulate wheel pressure as required. Use of the algorithm to control the electromagnetic poppet valves achieves the commanded pressure at a vehicle's brakes reliably and with good control in all states of flow through the valve. The algorithm is a function of the existing pressure within the system and whether there is bulk or leakage flow through the valves.

摘要： A method is provided for detecting a rollover event of a vehicle. A lateral kinetic energy of the vehicle is determined in response to vehicle longitudinal velocity and vehicle side slip angle. A lateral acceleration of the vehicle is measured. A tire normal force is measured. A rollover potentiality index is determined in response to the lateral kinetic energy and the lateral acceleration. A rollover index is determined by weighting the rollover potentiality index by a factor of the lateral acceleration and by a factor of the tire normal force. A comparison is made to determine if the rollover index is above a predetermined threshold.

摘要： A brake control system determines when a wheel is unstable or stable during a braking condition. An unstable wheel is determined when the wheel speed is different from the estimated vehicle speed by greater than a fixed amount. When the wheel is determined to be unstable, an amount of brake pressure reduction is determined according to a proportional-plus-integral compensation. The proportional-plus-integral compensation is a function of the difference between the wheel speed and the estimated vehicle speed, as well as a wheel deceleration value. When the wheel is determined to be stable, brake pressure is applied according to an exponential rate. A hold mode is entered when the wheel is determined to be no longer decelerating during a dump cycle.

摘要： The present invention determines a longitudinal wheel speed of an individual wheel from an angular rate signal from a wheel rotation sensor. Vehicle suspension information or operating characteristics are input to a suspension system mathematical model to determine instantaneous rolling radius, taking into account changes in tire rolling radius resulting from vertical motion of the road surface. Improved accuracy of wheel speed permits less severe filtering of wheel speeds in detecting wheel slip and/or modified speed and acceleration thresholds in slip control.

摘要： A method of controlling an advanced chassis control system of a vehicle such as an anti-lock brake system, traction control system, vehicle stability control system, or roll control system affecting the vehicle dynamic performance and safety is disclosed. A control unit controls the operation of the advanced chassis control system based at least in part upon predictions of force generating characteristics of tires of the vehicle and driver input signals. The advanced chassis control system of the vehicle is controlled in one manner if the tire is determined to be inflated, controlled in another, different manner if the tire is determined to be deflated. During normal driving, the chassis control systems can operate to control the vehicle according to the desires of the driver while accounting for at least one tire being deflated. During braking the controller can act to distribute braking forces in order to divert forces from the deflated tire to the inflated tires.
