Abstract: In a control apparatus for a vehicle, when a coast downshifting is performed in response to a downshifting command from a vehicle operator during braking operation under the fuel cut control, the braking force of the wheel brake is increased so as to increase the deceleration. This makes it possible to achieve a predetermined deceleration with a good response to the deceleration request of the vehicle operator represented by the downshifting command. The control apparatus is structured to decrease the braking force of the wheel brake such that the increase in the engine braking force is offset by the inertia caused by the rise in the engine speed resulting from downshifting upon the coast downshifting due to the vehicle speed increase. The control apparatus for the vehicle, thus, reduces the shock caused by the sharp increase in the engine braking force.

Abstract: A traction control system for a vehicle has a sub-throttle valve provided in an intake passage of the engine in series to a main throttle valve which is operatively connected to an accelerator pedal to open and close in response to operation of the accelerator pedal. An engine output controller controls opening of the sub-throttle valve to control the output of the engine so that the slip value of the driving wheels converges on a target slip value. The engine output controller once moves the sub-throttle valve to an initial opening when the slip value of the driving wheels exceeds the target slip value and then controls the opening of the sub-throttle valve to control the output of the engine so that the slip value of the driving wheels converges on a target slip value. The initial opening is set to be a fixed value when the opening of the main throttle valve is not larger than a predetermined opening and to be substantially equal to the opening of the main throttle valve when the opening of the main throttle valve is larger than the predetermined opening. The fixed value is not smaller than the predetermined opening of the main throttle valve.

Abstract: A brake booster for holding the braking action even if the brake pedal is released. The booster has a low pressure chamber and a variable pressure chamber with a diaphragm therebetween for moving the output shaft to the brake cylinder. A valve mechanism mechanically controlled by the brake pedal switches a communication passage between the low and variable pressure chambers and an atmospheric pressure passage from the variable pressure chamber to the exterior. A first solenoid valve can close the communication passage between the low and variable pressure chambers irrespective of the brake pedal position so as to hold the braking. A second solenoid valve can control a passage between the variable pressure chamber and the low pressure source so that the braking release can be gently effected.

Abstract: The device comprises sensors for providing electrical signals indicative of the speed of the vehicle, the speed of rotation of the engine, the position of the accelerator pedal and the position of the brake pedal. An electronic monitoring and control unit connected to these sensors, activates actuator devices arranged to turn off the engine when, for a period of time of predetermined duration, the speed of rotation of the engine is less than a first predetermined value, the speed of the vehicle is less than a threshold value, and the accelerator pedal is released. This monitoring and control unit deactivates the actuator means and activates the electric starter motor when the signals provided by the sensors indicate that the speed of rotation of the engine is lower than a second predetermined value, less than the first, and the accelelator pedal (or the brake pedal) is depressed.
