Abstract: A vehicle control system for a vehicle includes an engine control device configured to automatically stop an engine of the vehicle during running of the vehicle; and a brake control device configured to execute an assisting control for increasing an output of a brake for restraining rotation of a wheel of the vehicle when a starting condition for starting the assisting control is satisfied, such that an amount of the output increased by execution of the assisting control becomes larger than an amount corresponding to an operational state of a brake operating member of the vehicle. The brake control device includes an automatic-stop assisting control portion configured, during an automatic stop state in which the engine is automatically stopped by the engine control device, to execute the assisting control in a manner different from a manner in which the assisting control is executed during an activation state of the engine.

Abstract: A pressure assisted park servo assembly for an automatic transmission includes a servo or spool valve which receives pressurized hydraulic fluid from various sources including two solenoid valves and transmission ports. The servo valve controls two flows of pressurized hydraulic fluid to a servo assembly to place the transmission in or release it from park. The improved park servo assembly exhibits enhanced operating speed.

Abstract: A system and a method for generating a line pressure of a continuously variable transmission (CVT) in a hybrid vehicle in which the line pressure of the CVT is maintained to be constant even in an idle stop state of an engine. Steps may include detecting operation of a brake; determining whether an idle stop condition is satisfied; detecting a hydraulic pressure of a control valve for controlling the line pressure of the continuously variable transmission when the idle stop condition is satisfied; comparing the hydraulic pressure of the control valve with a predetermined value; generating a pressure difference in the chamber when the hydraulic pressure of the control valve is smaller than or equal to the predetermined value; and actuating a cylinder for generating the line pressure according to the pressure difference in the chamber.

Abstract: The invention relates to a parking brake system for transmissions of motor vehicle, especially for an automatic transmission and an automated selector transmission, having one parking brake for blocking or releasing the transmission according to actuation signals of a control device, especially by a pawl engaging and disengaging in a parking brake gear connected with the output of the transmission, an electric operative connection between the control device in the interior of the motor vehicle and the parking brake, a spring accumulator (9) for actuating the parking brake and a pressure-controlled release device of the parking brake. It is proposed to load the release device (10) when releasing the parking brake with a negative pressure independent of the transmission and which is preferably taken from the suction system (15) of the internal combustion engine of the motor vehicle or from a negative pressure brake force booster of the motor vehicle.

Abstract: A cutter has a drive motor and a drive shaft. A rotating cutting tool is connected to the drive shaft. A centrifugal clutch is connected between the drive motor and the drive shaft. A frictional brake having a brake drum and a brake element positioned on the brake drum to achieve a braking effect is provided. The frictional brake is connected to the drive shaft. A servo device, which includes a folding bellows, is connected to the frictional brake for releasing the brake element from the brake drum to cancel the braking effect. A switching device for activating the servo device is provided.
