20200156431 · 2020-05-21 ·

The present disclosure relates to an apparatus and method for controlling a lift axle of a vehicle. To assist with braking according to an operation of a forward collision avoidance (FCA) system by using the lift axle in an emergency braking situation, the vehicle lift axle control apparatus includes a lift axle actuator that drives the lift axle of the vehicle, an interworking device that interworks with the FCA system, and a controller that controls the lift axle actuator based on information obtained from the FCA system.

SHOCK-ABSORBING FRONT FORK ASSEMBLY OF MOTORCYCLE
20200140032 · 2020-05-07 ·

A shock-absorbing front fork assembly of a motorcycle includes a front fork, a pressure buffering cylinder and a control valve disposed between the front fork and the pressure buffering cylinder and electrically connected with a brake system to control the communication between the front fork and the pressure buffering cylinder according to the operation of the brake system. When the brake system is not actuated, the control valve is open to make the front fork communicate with the pressure buffering cylinder, thereby making the spring supporting force relatively smaller. When the brake system is actuated, the control valve is close to make the front fork not communicate with the pressure buffering cylinder, thereby making the spring supporting force relatively larger. Therefore, the spring supporting force is adjusted by the brake operation, that raises the riding comfort and safety.

Automatic shutoff system for a motor vehicle
10632845 · 2020-04-28 ·

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.

Situation detection in active suspensions
10603972 · 2020-03-31 · ·

A method for controlling an operating mode of a controller for at least one suspension component of an at least partially active suspension of a vehicle.
