The present invention provides a control method for automatic holding, a vehicle's brake system and a brake control module thereof. The vehicle's brake system comprises two brake control modules and electromechanical brakes controlled by the brake control modules, a drive motor and a drive motor controller for controlling the drive motor. The control method comprises: after the vehicle transitions from moving to stationary, controlling the electromechanical brakes to continuously provide a brake torque, wherein the brake torque is a sum of the effective brake torque and a margin brake torque; and continuously outputting a drive-off signal to the drive motor controller to control the drive motor not to provide drive torque; until a driver requested drive torque is continuously increased to a critical torque which is close to the effective brake torque.

A transmission is subject to gear shift management that provides for shifting gears in a controlled manner in order to provide for a simplification of part and reduction in system complexity. In particular, a range synchronizer component can be replaced with a simplified range jaw clutch, without incurring a requirement for an installation of other components such as a motor generator or starter-generator.

Method of controlling a pickup manoeuvre of a hybrid vehicle

A method of controlling a pickup manoeuvre of a hybrid vehicle is actuated with an engine off, an electric motor active and a first clutch being open. In a first phase of the manoeuvre, vehicle advancement is obtained by progressively closing the second clutch so that the input shaft is set in rotation with an increasing speed, while the motor rotates at an increasing speed higher than a speed of the input shaft with the second clutch in a slip condition. Upon a request for starting the engine, the first clutch is progressively closed so that the engine starts to be driven by the motor, while the second clutch is kept in the slip condition, which is maintained until the engine and motor rotate substantially at a same speed, higher than the speed of the input shaft, and once this condition is reached, closing of the second clutch is started.

Powertrain device for vehicle

The powertrain device for a vehicle includes an engine and an automatic transmission, the automatic transmission includes a plurality of friction fastening elements for selectively switching motive power transmitting paths, a predetermined friction fastening element among the plurality of friction fastening elements is a travel-start friction fastening element performing slip control in a travel start, and the powertrain device includes, between the engine and the automatic transmission, a motive power connection-disconnection clutch which is released at least in an engine start and is fastened earlier than the travel-start friction fastening element in a travel start of the vehicle.

DRIVING SUPPORT DEVICE

The posture of the driver is detected from the driver head portion, and the detected value and the driver mounting determination value are used to determine that the driver is pushing the vehicle and obtain the vehicle pushing command value. Converts the vehicle pushing command value to the target vehicle pushing assistance vesicle speed, determines whether vehicle pushing assistance can be performed based on the driver's posture and the vehicle condition, and outputs the vehicle pushing assistance permission determination. Then, from the target vehicle pushing assistance vehicle speed and the vehicle pushing assistance permission determination, the control amount for the vehicle power source that assists the vehicle pushing is calculated and output.
