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.

A hydraulic suspension system controller is disclosed, comprising a controller in operable communication with a hydraulic system of a vehicle. The controller includes at least one display, at least one indicator, and a plurality of buttons, wherein each button corresponds to a function of the controller, and wherein each function effects the hydraulic system to raise and lower at least one of a plurality of solenoids each in operable communication with a hydraulic actuator to extend or contract the hydraulic actuator. A fail-safe module is in operable communication with the controller, the fail-safe module receiving a plurality of signals from a sensor array to monitor the hydraulic system.

A method for improving the safety and comfort of a vehicle driving over a railroad track, cattle guard, or the like. The method may include receiving, by a computer system, one or more inputs corresponding to one or more forward looking sensors. The computer system may also receive data characterizing a motion of the vehicle. The computer system may estimate, based on the one or more inputs and the data, a motion of a vehicle with respect to a railroad track, cattle guard, or the like extending across a road ahead of the vehicle. Accordingly, the computer system may change a suspension setting, steering setting, or the like of the vehicle to more safely or comfortably drive over the railroad track, cattle guard, or the like.

The present invention makes it possible to appropriately grasp a stop cause when a vehicle stops. An ECU 5, which controls a vehicle including wheels and a vehicle body connected to the wheels includes: a wheel stop detection unit 138 that detects a stop of the wheels; a vehicle body stop detection unit 133 that detects a stop of the vehicle body; and a stop cause determination unit 141 that determines a stop cause of the vehicle based on a stop timing of the wheels detected by the wheel stop detection unit 138 and a stop timing of the vehicle body detected by the vehicle body stop detection unit 133. The stop cause determination unit 141 may determine that the stop cause is contact of the vehicle body with an obstacle when the stop timing of the vehicle body is earlier than the stop timing of the wheels.

A method for controlling the safe operation of a rear axle of a set of combined axles powered by a motor vehicle, particularly for a vehicle designed to carry loads and which have 6×4, 8×4 or 10×4 type traction configurations, or tridem models formed by three drive axles. The method includes a set of steps and activities that ensure proper and safe operation of systems and mechanisms for uncoupling and raising a rear axle of a vehicle, and more specifically checking a status of certain operating parameters of the rear axle and of the vehicle itself in order to permit or prevent uncoupling and coupling, as well as raising and lowering of the rear axle of the vehicle.

A method for the automated control of the longitudinal movement of a motor vehicle having an automated positive acceleration process in a longitudinal direction of the vehicle and an automated deceleration in the longitudinal direction of the vehicle. An acceleration variable is determined based on a jerk value and limited in terms of absolute value. And the jerk value is in turn determined in a driving mode in which, starting from a vehicle actual longitudinal speed and a vehicle actual longitudinal acceleration, the motor vehicle is adjusted to a predeterminable vehicle longitudinal speed taking into account a predeterminable maximum positive driving mode vehicle longitudinal acceleration, a predeterminable maximum driving mode vehicle longitudinal deceleration and at least one predeterminable driving operating mode jerk absolute value which limits the jerk.

Disclosed herein are a driving unit and a robot cleaner having the same. The robot cleaner has a configuration in which an elastic member is supported so that an angle formed between the elastic member and a rotation shaft of the driving unit is provided in a predetermined range to offset a decrease in an elastic force generated while the robot cleaner is driving on a surface having steps and a driving wheel protrudes downward from the robot cleaner. Accordingly, there is the effect where a traction force is maintained at a predetermined level for maintaining the driving performance of the robot cleaner even while the robot cleaner is driving and the driving wheel is lowered to decrease the elastic force of the elastic member.
