摘要： A method for controlling regenerative braking of a hybrid commercial vehicle that includes a main brake and an auxiliary brake is provided. The method includes determining whether a braking request condition of the vehicle is satisfied based on a state data and generating a request braking amount based on the state data when the braking request condition is satisfied. When an operation switch of the auxiliary brake is on an auxiliary braking amount of the auxiliary brake is generated. A final braking amount is generated based on the request braking amount and the auxiliary braking amount. A regenerative braking amount is generated based on the final braking amount and braking of the vehicle is performed based on the final braking amount.

摘要： The invention relates to a method for operating a motor vehicle (1) which has at least one electric machine (7) which can be/is operatively connected to at least one driven wheel (6) of the motor vehicle (1), and a safety device (13) which is assigned to a driven wheel (6), is independent of the electric machine (7) and when necessary applies a positive or negative torque to the driven wheel (6), wherein the electric machine (7) is operated by an inverter (8). There is provision that the inverter (8) is monitored for incorrectly set torques, and that the safety device (13) is actuated as a function of a detected incorrect torque.

摘要： Electrically powered vehicles may be equipped with both mechanical braking systems and regenerative braking systems. Regenerative braking systems improve vehicle efficiency by returning a portion of the energy lost in deceleration to the battery of the electrically powered vehicle. An electrically powered vehicle controller that provides collision avoidance functionality can maximize the energy returned to the battery of the electrically powered vehicle by maximizing the use of regenerative braking for collision avoidance. A first braking mode can include only regenerative braking for objects greater than the minimum regenerative stopping distance. A second braking mode can include composite braking using both mechanical and regenerative braking. The electrically powered vehicle controller determines the maximum regenerative braking level at least based on data provided battery charge level or battery state sensors.

摘要： A system and a method are provided to control and distribute a regenerative braking force in an autonomous vehicle based on a resistance generated to a traveling vehicle. The method includes: a first step of comparing a tractive resistance and a target braking force in a section from an autonomous vehicle acceleration off time point to a first time point in a braking section; and a second step of comparing a sum of the tractive resistance and a maximum regenerative braking force with the target braking force in a section from the first time point to a second time point in the braking section.

摘要： A method for controlling a hydraulic brake system during a regenerative braking process where a displacement of a hydraulic fluid in the direction of a wheel brake is performed by means of a brake cylinder and at least one volume fraction of the hydraulic fluid is conducted via a pressure dissipation valve, which is situated in an open position, into an accumulator. In the method, furthermore, the pressure dissipation valve is adjusted in the direction of a closed state, in order to realize an increase of a hydraulic braking torque effected by the wheel brake, if an overall braking torque which is made up of the hydraulic braking torque and a generator braking torque effected by an electric machine is lower than a braking torque demand, and if the generator braking torque lies below a braking torque limit of the electric machine.

摘要： Methods and systems are provided for operating a hybrid vehicle during operating conditions where vehicle braking is requested. In one example, regenerative braking is allocated to vehicle axles responsive to wheel torques of respective vehicle axles in response to an anti-lock braking system being activated. Additionally, friction braking torque is allocated to vehicle axles responsive to the anti-lock braking system being activated.

摘要： A monorail vehicle includes a chassis supporting a vehicle body that includes a passenger floor, a first side wall, and a second side wall and first and second propulsion systems. Each propulsion system includes an electric motor and a drive wheel coupled to a rotor of the electric motor. Each electric motor and the drive wheel coupled to the rotor of the electric motor are positioned on both sides of an imaginary plane extension of the passenger floor. First and second shells cover portions of the first and second propulsion system. The first shell is positioned proximate to the first side wall and defines a first space between the second side wall. The second shell is positioned proximate to the second side wall and defines a second space between the first side wall.
