A suspension apparatus includes: a damping device which damps a force generated between a vehicle body and a wheel; and a control section which controls a damping force of the damping device. The control section includes a multiplication section which multiplies a longitudinal acceleration of the vehicle body detected by a longitudinal acceleration sensor and a differential value of the longitudinal acceleration to thereby obtain a multiplication value.

A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame are disclosed. The vehicle including at least one adjustable shock absorber having an adjustable damping characteristic.

An automatic shutoff system for a motor vehicle, the automatic shutoff system including a front suspension system disposed at a front portion of the motor vehicle, the front suspension system comprising at least one spring wrapped around at least one arm, at least one sensor disposed on the at least one arm to sense when the at least one spring has been jarred at a predetermined intensity, a curb jump detection system to receive at least one signal from the at least one sensor when the at least one spring has been jarred at the predetermined intensity, and to process the at least one signal to determine whether a curb has been jumped by the front suspension system, and a computer system to receive a signal from the curb jump detection system when the curb jump detection system determines that the curb has been jumped by the front suspension system, and to control a motor to shut off.

System and method for improving braking efficiency by increasing the magnitude of a frictional force between a tire of a vehicle wheel and a road surface. Braking efficiency may be improved by controlling the normal force applied on the wheel, with an active suspension actuator, based on the wheel's slip ratio.

A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame are disclosed. The vehicle including at least one adjustable shock absorber having an adjustable damping characteristic.

Method to control active shock absorbers of a road vehicle. Each active shock absorber is part of a suspension connecting a frame to a hub of a wheel and is provided with an actuator. The control method comprises the steps of: determining a longitudinal acceleration and a transverse acceleration of the road vehicle; establishing a desired lowering of a centre of gravity of the road vehicle depending on the longitudinal acceleration and on the transverse acceleration; and controlling the actuator of each active shock absorber so as to obtain the desired lowering of the centre of gravity.

A method for controlling a suspension system is disclosed. The method includes obtaining a first group of signals and a second group of signals; determining whether a trigger condition is met; determining an adjustment signal for adjusting the suspension system based on related signals of the suspension system, in response to the trigger condition being met; using the adjustment signal on the suspension system; the first group of signals being signals related to a comfort braking control system and the second group of signals being signals related to driving expectations. A system for controlling a suspension system and a suspension control system are also disclosed.

A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame are disclosed. The vehicle including at least one adjustable shock absorber having an adjustable damping characteristic.

An air supply control arrangement for a heavy-duty vehicle comprising a lift axle is provided. An electronically controlled brake valve device allows, when open, pressurized air to be passed to the brake chamber of the lift axle. A pressurized air source supplies pressurized air to the electronically controlled brake valve device along a supply passage. A pilot control valve provided between the pressurized air source and the electronically controlled brake valve device can restrict air flow through the supply passage. A pressure-responsive element actuates the pilot control valve when the pressure in the lift bellow is increased so that the lift axle is raised to a lift condition. The pressure-responsive element closes the pilot control valve. When the pressure in the lift bellow is reduced so that the lift axle is lowered to a ride condition then the pressure-responsive element is deactivated to allow opening of the pilot control valve.

This vehicle control device is provided with: a control unit for executing one-pedal control, that is, the control for accelerating a vehicle when a single pedal is depressed from a predetermined reference point of a pedal stroke, and for decelerating the vehicle when the pedal is released from the reference point; and a determination unit for determining whether or not a rate of change in a pedal operation amount when the pedal is released is equal to or greater than a first threshold value. The control unit performs control for increasing a braking force when the rate of change is equal to or greater than the first threshold value.
