摘要:
A damper control device includes a pitching angular velocity detection unit that detects a pitching angular velocity of a vehicle body, a front wheel side pressure detection unit that detects a pressure of a compression side chamber in a front wheel side damper, and a rear wheel side pressure detection unit that detects a pressure of a compression side chamber in a rear wheel side damper. The damper control device controls the pressure of the compression side chamber in the front wheel side damper and the pressure of the compression side chamber in the rear wheel side damper based on the pitching angular velocity, the pressure of the compression side chamber in the front wheel side damper and the pressure of the compression side chamber in the rear wheel side damper.
摘要:
A system and method for sensing vehicle global pitch angle and rate that uses global velocities measured from a single antenna global positioning system (GPS) receiver together with sensor fusion algorithms involving sensor signals and other computed signals. This constructed, or computed, vehicle body's pitch angle may replace the role of a pitch rate sensor in an integrated stability control system. Namely, it achieves enhanced vehicle state estimation without the need for a pitch rate sensor.

A control system (11) for a vehicle (10) includes vehicle dynamics sensors (35-47) providing a vehicle dynamics signal. Tire monitoring system sensors (20) in each wheel generate tire signals including temperature, pressure and acceleration data. A controller (26) communicates with the tire monitoring system sensors (20) and at least one vehicle dynamics sensor, and generates a brake signal as a function of the multi-axis acceleration data of the tire signals. The brake signal is transmitted to a brake system (64) to apply a brake torque in response to the brake signal.

A sprung mass damping control system of a vehicle, which aims to suppress sprung mass vibration generated in a vehicle body of a vehicle provided with at least a motor-generator (first and second motor-generators) as a drive source, includes a sprung mass damping control amount calculating device that sets a sprung mass damping control amount for suppressing the sprung mass vibration, and a drive source control device (a motor-generator control device) that executes sprung mass damping control by controlling a motor-generator control amount of the motor-generator to realize the sprung mass damping control amount.

A vehicle control device and a vehicle are provided with compatibility between high grip performance and fuel efficiency. When a camber angle of a wheel is adjusted as a negative camber, the ground contact pressure on a first tread is increased and the ground contact pressure on a second tread is decreased, thus providing the high grip performance. On the other hand, when the camber angle of the wheel is adjusted as a positive camber, the ground contact pressure on the first tread is decreased and the ground contact pressure on the second tread is increased, thereby reducing rolling resistance and achieving fuel saving. By adjusting the camber angle of the wheel, compatibility can be provided between high grip performance and fuel saving which otherwise conflict with each other.

A method and device for roll stabilization of a motor vehicle are provided. On the basis of a measured transverse acceleration or a calculated transverse acceleration of the motor vehicle, actuating signals are generated for actuators which are associated with a front axle and a rear axle of the motor vehicle and which provide support torques on the front axle and/or on the rear axle for roll stabilization. To ensure a satisfactory self-steering effect of the motor vehicle, a torque distribution between the support torque provided on the front axle and the support torque provided on the rear axle is modified on the basis of a first signal which allows conclusions to be drawn concerning the actuation of a gas pedal, and/or on the basis of a second signal which allows conclusions to be drawn concerning the actuation of a brake pedal.
摘要:
A control valve and feedback system has three operating states including a lifting state, a neutral state, and a lowering state. The feedback control system comprises a cylinder, a pump, a reservoir for holding working fluid, and a control valve. The control valve comprises a valve body having first and second ends with a bore defined therebetween. The valve body further comprises an inlet port, a return port, a first work port and a second work port. The inlet port, return port, and first and second work ports are defined in the valve body. The inlet port communicates with the bore and the pump. The return port is in fluid communication with the bore and the reservoir. The first work port is also in communication with the bore and the cylinder in the lifting state. The control valve is plumbed backwards so that the first work port and the second work port are in fluid communication in the lowering state. The valve also comprises a check valve disposed in the first work port. The first check valve is adapted to achieve the neutral state and being selectively adjustable to achieve said lowering state.
