To provide a vehicle drive device capable of efficiently driving a vehicle by using in-wheel motors without falling into the vicious cycle between enhancement of driving via the motors and an increase in vehicle weight. The present invention is a vehicle drive device that uses in-wheel motors to drive a vehicle and includes in-wheel motors (20) that are provided in wheels (2b) of a vehicle (1) and drive wheels, in which the in-wheel motors generate the maximum output power in a high revolutions range equal to or more than a predetermined number of revolutions that is more than zero.

A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

An acceleration sound generation device for a vehicle using at least one of an acceleration operation of the vehicle, an acceleration force generated by the acceleration operation, and an acceleration state obtained by the acceleration force as a control parameter. The acceleration sound generation device includes a sound generation unit and an acceleration sound delay unit. The sound generation unit generates an acceleration sound in a vehicle passenger compartment in response to an acceleration sound signal that is generated based on the control parameter. The acceleration sound delay unit delays output of the acceleration sound by the sound generation unit such that the acceleration sound changes and is delayed with respect to a change in the control parameter. The acceleration sound delay unit sets a delay degree of the acceleration sound at a rising time of the control parameter separately from at a falling time of the control parameter.

A small electric vehicle includes: a vehicle body that has a forward and backward direction, and a width direction; left and right driving wheels provided apart in the width direction of the vehicle body; left and right motors connected so as to respectively transmit power to the left and right driving wheels; an operation unit that includes a joystick-type operation piece; and a control unit for controlling the left and right motors according to an amount of operation on the operation piece, wherein the control unit is configured to execute deceleration and stop control when the operation piece is returned to the neutral position during travel, and execute rapid stop control irrespective of an amount of operation in left and right directions when the operation piece is tilted backward during forward travel at a speed equal to or greater than a predetermined threshold.

A control system for a vehicle is provided, which includes a driving force source configured to generate torque for driving drive wheels, a steering wheel, a steering angle sensor, and a controller. Based on the detected steering angle, the controller reduces the driving torque to add deceleration to the vehicle when the steering wheel is being turned in one direction, and increases the torque to add acceleration when the steering wheel is being turned back in the other direction. The controller controls the torque, when the steering wheel is being turned in the returning direction from a state where it is turned in the one direction, so as to add forward acceleration until the steering wheel returns to a neutral position, and when the steering wheel is then being turned in the other direction after passing through the neutral position, so as not to add the forward acceleration.

An eco-friendly vehicle and a hill descent control method therefor are provided to enable stable driving on a downhill road. The method includes detecting a downhill road inclination based on a request for hill descent control and determining an average inclination and an inclination variation width based on the recognized downhill road inclination. First braking force of a main braking source from a motor and a hydraulic pressure brake system based on the average inclination and the inclination variation width, and second braking force of an auxiliary braking source from the motor and the hydraulic pressure brake system for each driving wheel based on a target speed set with respect to the hill descent control and a speed of each driving wheel are determined. The first and second braking force are output by a corresponding braking source from the motor and the hydraulic pressure brake system.

To provide a vehicle drive device capable of efficiently driving a vehicle by using a motor without falling into the vicious cycle between enhancement of driving via the motor and an increase in vehicle weight. The present invention is a vehicle drive device (10) having a motor for driving the wheels of a vehicle and includes a front wheel motor (20) for driving front wheels (2b) of a vehicle (1) and a battery (18) and a capacitor (22) that supply electric power for driving the front wheel motor (20), in which the voltage of the battery (18) and the capacitor (22) connected in series is applied to the front wheel motor (20) and the capacitor (22) is disposed between the left and right front wheels (2b) of the vehicle (1).

According to at least one embodiment, the present disclosure provides an electrohydraulic brake system including main brake assemblies, electronic parking brakes (EPBs), a main control unit, and a redundancy control unit (RCU). The main brake assemblies generate a braking force in one or more front wheels and one or more rear wheels of a vehicle. The electronic parking brakes (EPBs) generate a braking force to one of the front wheels and rear wheels. The main control unit is configured to control the operation of the main brake assembly. The redundancy control unit (RCU) is configured to control the operation of the electronic parking brake. Here, the redundancy control unit performs, upon determining that a malfunction occurs in a braking function of the main control unit, a slip control on the vehicle by using the electronic parking brake based on signals from one or more wheel speed sensors.
