A vehicle includes a collision determination ECU determining whether a possibility of collision is present, based on a detection result of a detection sensor detecting outside of the vehicle, a motor, a boosting circuit and a battery supplying a high voltage to the motor, and an electric suspension control ECU controlling the boosting circuit and the motor, and in a case where the collision determination ECU determines that the possibility of collision is present, the electric suspension control ECU limits the supply of the high voltage to the motor.

A vehicle includes a high voltage component such as an electric actuator, an electric suspension control ECU, a battery, a signal line which transmits, to the electric suspension control ECU, a detection signal of a sensor disposed in the electric actuator, a high voltage line which supplies a high voltage from the battery to the electric actuator, and a fixing member which fixes the signal line and the high voltage line to a vehicle body, a length of the signal line from the fixing member to the electric actuator is shorter than a length of the high voltage line from the fixing member to the electric actuator, and the electric suspension control ECU suppresses the supply of the high voltage to the electric actuator, in a case where abnormality occurs in the signal line.

In some embodiments, a rapid-response active suspension system controls suspension force and position for improving vehicle safety and drivability. The system may interface with various sensors that detect safety critical vehicle states and adjust the suspension of each wheel to improve safety. Pre-crash and collision sensors may notify the active suspension controller of a collision and the stance may be adjusted to improve occupant safety during an impact while maintaining active control of the wheels. Wheel forces may also be controlled to improve the effectiveness of vehicle safety systems such as ABS and ESP in order to improve traction. Also, bi-directional information may be communicated between the active suspension system and other vehicle safety systems such that each system may respond to information provided to the other.

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.

A system and method for accounting for a mismatch that exists between a vehicle's bumper and potential impact point using an active suspension is disclosed. The system and method determine that a mismatch exists between a vehicle's bumper and a potential impact point and actuate the suspension to account for the determined mismatch. The system and method account for the mismatch existing between a vehicle's bumper and a potential impact point using a sensor for detecting that a mismatch exists between the bumper and the potential impact point, and a suspension configured to be actuated to account for the sensed mismatch to enable improved alignment of the bumper and the potential impact point.

In the front lower arm, a ball joint bracket to which a ball joint to be coupled to a knuckle is attached is welded to an outer end of a lower arm body in the left and right direction of the vehicle. A spindle member connected to a lower end of a shock absorber is provided on a front side of the ball joint bracket in the front and back direction of the vehicle so as to protrude forward. A welding part between the lower arm body and the ball joint bracket is inclined in plan view, toward an outside in the left and right direction from a front part to a rear part of the welded part in the front and back direction. An extension of a central axial line of the spindle member is arranged so as to intersect with the welded part.
