PURPOSE:To enable braking auto cruising with high reliability, safety and responsiveness by providing an auxiliary brake for applying braking force according to a car velocity to a driving force transmission system at the time of reaching, the minimum fuel supply quantity. CONSTITUTION:Engine brake means comprises exhaust brake means 5 for opening and closing an exhaust passage 3 and the turbine b...

PURPOSE:To prevent slip and spin simply and securely by detecting the slip and spin of each of four wheels based on the rotating speed of each of four wheels and giving a braking force at the time of slipping and lowering an engine output at the time of spinning. CONSTITUTION:The output shaft 3 of a transmission 2 linked to an engine 1 is linked to a center differential device 4. The center differ...

PURPOSE:To obtain both the prevention of consumption in current, pumping loss, and noise and the improvement in responsiveness in the generation of a transmitting torque by limiting the generating timing of clutch engaging force while preventing controlling hunting. CONSTITUTION:A friction clutch element (e) for generating a transmitting torque which is variable in accordance with an engaging forc...

PURPOSE:To obtain a stable braking force by reducingly operating the braking capacity of an exhaust brake which closes an exhaust passage when the braking capacity of an auxiliary brake which loads a braking force corresponding to a vehicle speed on the crankshaft of an engine is in the vicinity of its limit. CONSTITUTION:An exhaust brake 5 consists of an exhaust brake valve 7 for increasing the p...

PURPOSE:To avoid giving a feeling of acceleration to a driver at the time of high engine speed with a throttle valve being totally closed by providing a correcting means for correcting the target rotating speed of a primary pulley in the direction of lowering an engine output torque. CONSTITUTION:While driving a vehicle, an actual change gear ratio is calculated 60 according to a primary pulley ro...

PURPOSE:To prevent unnecessary adjustment for the releasing clutch when an adjusting element has a short-circuit failure by adjusting the releasing clutch position when the adjusting element for adjusting the clutch position for releasing the braking force is on-operation from second time and on. CONSTITUTION:There is provided an adjusting switch SW for adjusting the clutch position for releasing ...

PURPOSE:To improve safety by generating an alarm signal when a car velocity or braking force holding time becomes more than a preset value during holding the braking force in which a solenoid check valve for holding braking force is energized. CONSTITUTION:A solenoid check valve 15 for braking is interposed in an oil pressure route 16b for feeding braking oil to a wheel brake 17 at the time of bra...

PURPOSE:To prevent unnecessary positioning adjustment when an adjusting element has a short-circuit failure by enabling the adjustment within a fixed range every time an adjusting element for adjusting the position of a braking force releasing clutch is operated from on-state to off-state while a neutral switch is off. CONSTITUTION:There is provided an adjusting switch SW for adjusting the positio...

PURPOSE:To enable safe holding and releasing of braking force by holding braking force by a solenoid check valve as far as the neutral state is not released even if the clutch position is a little to the connection side than the braking force releasing clutch position when a neutral switch is turned off. CONSTITUTION:There is provided an adjusting switch SW for adjusting the clutch position for re...

PURPOSE:To improve braking ability and reliability by providing an auxiliary brake for applying braking force according to a car velocity and an exhaust brake for substantially increasing the controllability of the brake. CONSTITUTION:A turbine brake 6 as an auxiliary brake is adapted to apply braking force according to a car velocity to a crankshaft 4 to brake at the time of engine brake. At the ...

PURPOSE:To enable braking auto cruising with high reliability, safety and responsiveness by providing an auxiliary brake for applying braking force according to the change rate of a car velocity in a driving force transmission system. CONSTITUTION:Engine brake means comprise exhaust brake means 5 for opening and closing an exhaust passage 3, and turbine brake means 6 for applying braking force to ...
