摘要： A battery-temperature raising apparatus includes a battery, a transmission, an oil pan, a heat-retaining oil tank, a heat exchanger, a first valve, a temperature sensor, and a control unit. The transmission includes a transmission mechanism that converts torque and a clutch capable of braking a wheel. The oil pan and the oil tank are disposed in the transmission and are in communication with the heat exchanger that exchanges heat between the battery and oil. The first valve opens and closes a path joining the oil tank and the heat exchanger. The control unit generates braking force by controlling engagement force of the clutch depending on an amount of depression of a brake pedal. The control unit supplies the oil stored in the oil tank to the heat exchanger by opening the first valve when a temperature of the battery detected by the temperature sensor is below a predetermined temperature.

摘要： A method of controlling torque of a drive system of an electric vehicle is to provide a drive system torque command generation and torque control method of an electric vehicle capable of generating torque and improving vehicle responsiveness and behavioral responsiveness. The method of controlling torque of a drive system of an electric vehicle includes performing backlash control for limiting a torque slope of a front wheel torque command while the front wheel torque command passes through a backlash band, which is a torque region where there is possibility that backlash occurs in a front wheel-side drive system, and generating a braking torque command for generating a friction braking torque while the backlash control is performed.

摘要： Disclosed is a brake apparatus capable of minimizing the stress of valves. The brake apparatus comprises: a first wheel cylinder provided in a first wheel; a second wheel cylinder provided in a second wheel; a first outlet valve for controlling discharge of brake oil from the first wheel cylinder; a second outlet valve for controlling discharge of the brake oil from the second wheel cylinder; and a controller which opens and then closes one of the first and second outlet valves in response to a first braking command generated when a brake pedal deviates from a standard position, and opens and then closes the other outlet valve of the first and second outlet valves in response to a first brake suspending command generated when the brake pedal is restored to the standard position.

摘要： A method of assisting deceleration during a stop of a motor vehicle having a drivetrain including a traction motor, a road wheel operatively connected to the drivetrain, a friction brake configured to decelerate the road wheel, and an electronic controller includes detecting, via the electronic controller, a request to stop the vehicle. The method also includes commanding the traction motor to provide regenerative braking in response to the request to stop the vehicle. The method additionally includes determining a current vehicle operating state. The method also includes determining an amount of brake drag torque to be generated by the friction brake based on the current vehicle operating state. The method further includes commanding an application of the determined amount of the brake drag torque in parallel with the regenerative braking, thereby operating the friction brake as a mechanical drivetrain damper while assisting the regenerative braking to stop the motor vehicle.

摘要： A vehicle braking control system includes a vehicle microphone, two front wheels and two rear wheels of a vehicle, two front brakes and two rear brakes, and an electronic brake pressure control module configured to selectively control an amount of brake pressure applied to the front brakes and the rear brakes. The vehicle control module is configured to detect, via the at least one vehicle microphone, a brake noise value in response to brake pressure applied to the front brakes and the rear brakes, determine whether the brake noise value exceeds a specified brake noise threshold, identify which of the front brakes and the rear brakes are generating a greater noise value in response to the brake noise value exceeding the specified brake noise threshold, and reduce brake pressure applied to the identified one of the front brakes and the rear brakes.

摘要： A motor performing power driving and regeneration has an inverter, a mechanical brake, a power storage device supplying energy to the motor, an accelerator operator controlling the motor to adjust a drive torque of a driving wheel, a mechanical brake operator controlling the mechanical brake to adjust a braking torque, a regenerative brake operator adjusting a braking torque of the driving wheel and recovering the energy into the power storage device, and a detector detecting a rotation speed of the motor. When the rotation speed of the motor is equal to or higher than a predetermined value, a predetermined braking torque, based on an operation amount of the regenerative brake operator, is generated by regenerative braking.

摘要： A control device includes a switching control unit, an information acquisition unit, and a difference acquisition unit. The switching control unit performs switching control that increases braking torque of the braking device while decreasing braking torque of the rotating electrical machine, when a vehicle is decelerated. The information acquisition unit acquires information on a state of the vehicle. The difference acquisition unit acquires a braking torque difference indicating a difference between braking torque required for keeping a stopped state of the vehicle and braking torque of the braking device, when the vehicle is stopped. After the information acquisition unit detects the stopped state of the vehicle, the switching control unit corrects output torque of the rotating electrical machine based on the braking torque difference.
