Abstract: A braking control apparatus includes a braking force control unit, a first abnormality detecting unit, a regenerative brake stopping unit, and a braking force compensating unit. The braking force control unit is configured to perform a braking force control by causing an engine brake, a regenerative brake, and a friction brake to operate in cooperation with each other. The regenerative brake stopping unit is configured to disconnect the regenerative brake from the braking force control, when an abnormality of the regenerative brake is detected by the first abnormality detecting unit. The braking force compensating unit is configured to perform a braking force compensation that utilizes the friction brake, from the detection of the abnormality of the regenerative brake until the regenerative brake is disconnected from the braking force control, by performing a feedback control on a deceleration rate at a time when the abnormality of the regenerative brake is detected.

Abstract: The braking control device includes a control amount derivation unit that derives a target vehicle braking force representing a target value of a vehicle braking force applied, and a braking control unit that controls a regenerative braking device and a frictional braking device based on the target vehicle braking force. When the target vehicle braking force is increased, the braking control unit executes a braking force application process of increasing the frictional braking force applied to the wheel so that such frictional braking force becomes larger than the regenerative braking force applied to the wheel. When the target vehicle braking force is increased, the braking control unit executes a switching process of switching at least a part of the frictional braking force applied to the wheel to the regenerative braking force to increase the regenerative braking force applied to the wheel after execution of the braking force application process.

Abstract: A method for controlling wheel slip in a braking system of a vehicle involves receiving, by a wheel slip control sub-module of a wheel slip main control module a first plurality of input information, determining, by the wheel slip control sub-module, a braking torque request to be applied to a corner of the vehicle and a braking torque control component, providing the braking torque request, the braking torque control component, and an enabled wheel slip control confirmation value, to a braking regeneration sub-module of the main wheel slip control module, receiving, by the braking regeneration sub-module, a second plurality of input information, and determining a regenerative braking torque command as a function of the braking torque request or of the braking torque control component, based on a status of an enabling input signal. The braking regeneration sub-module determines a dissipative braking torque command as a function of the braking torque request and of the regenerative braking torque command.

Abstract: A braking control apparatus includes a driving information detector configured to detect a braking request from a driver while a vehicle is driving; and a vehicle controller configured to control a braking torque of the vehicle in response to the braking request from the driver, wherein the braking torque includes a regenerative braking torque formed by a motor and a hydraulic braking torque formed by a hydraulic brake, and wherein the vehicle controller is configured to perform regenerative braking using an initial regenerative braking torque determined by the braking request from the driver, using an initial regenerative braking torque determined by the braking request from the driver, and when wheel-slippage occurs, the vehicle controller reduces the regenerative braking torque to be less than the initial regenerative braking torque.

Abstract: The present disclosure relates to a method for braking a vehicle, a vehicle including a control unit configured to perform such a method and a computer program element for braking a vehicle. The method for braking a vehicle includes estimating a potential brake energy to be regenerated during a braking event, determining a threshold based on a regenerating capacity of a first axle drive unit, comparing the potential brake energy to be regenerated with the threshold, and switching a second axle drive unit to a regeneration mode for regenerating the brake energy in case the potential brake energy to be regenerated is higher than the threshold.

Abstract: 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.

Abstract: 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.
