摘要： An engine brake for a supercharged internal combustion engine for driving a motor vehicle is operated such that the working gas compressed during engine braking, prior to the end of the expansion cycle, is drawn at least partially from the working chambers of the engine through at least one throttle valve, with an exhaust turbocharger of the engine having an exhaust turbine with variable turbine geometry. The engine braking power is regulated based upon the travel of the throttle valve and/or an intake cross section of the exhaust turbine as a function of the operating parameters of the internal combustion engine and the vehicle driving speed. Upon issuance of a signal indicating a braking performance requirement from the driver, the required braking power is applied at least preferably through the engine brake.

摘要： A method of controlling an internal combustion engine when the engine is operating in an engine braking mode is provided. The engine operates in the engine braking mode and an exhaust valve for the cylinder is prematurely opened to dissipate power. The method includes controlling airflow to at least one cylinder based on a comparison of a desired mass airflow rate and an actual mass airflow rate such that the actual mass airflow rate tracks the desired mass airflow rate.

摘要： Method and apparatus for reversing the driving direction of a vehicle in motion, in which a movement of a gear selector to a position that indicates the new intended driving direction is detected (12). After the gear selector has assumed the new driving direction position, the vehicle's driving brakes are applied (14) depending upon the depression of the vehicle's gas pedal. The driving brakes (10) are applied proportionally to a change in position of the gas pedal. A speed of the engine (1) of the vehicle is increased with increased depression of the gas pedal. A gearbox (2) of the vehicle is disconnected (13) from the vehicle's engine (1) when the gear selector is detected to have been moved to the reverse driving direction position. A change (15) in the gearbox is effected from the current gear position to a position that indicates the selected gear for driving in the reverse direction after disconnection (13) of the vehicle's gearbox (2) from the vehicle's engine (1).

摘要： A vehicle auxiliary braking system is provided to accomplish a braking effect similar to engine braking inexpensively, to extend the life of the brakes, and to reduce the work cycle time in order to improve work efficiency. The system has a centrifugal sensor 20, an accelerator sensor 21, and a braking clutch engaging means that includes a braking hydraulic circuit 22. The centrifugal sensor 20 detects that the vehicle is traveling when the vehicle is moving at or above a prescribed speed. Accelerator sensor 21 detects when the depression amount of the accelerator pedal 6 is at or below a prescribed amount. The braking clutch engaging means engages the clutch that corresponds to the opposite travel direction when the vehicle is traveling at or above the prescribed speed and the accelerator depression amount is at or below the prescribed depression amount.

摘要： An accelerator pedal assembly that provides a hysteresis in pedal force-response upon actuation is provided. The accelerator pedal assembly includes a housing, an elongated pedal arm terminating at one end in a rotatable drum defining a curved braking surface, a brake pad having a curved contact surface substantially complementary to the braking surface and a bias spring device operably situated between the pedal arm and the brake pad. The pedal arm is rotatably mounted to the housing such that the curved braking surface rotates as the pedal moves. The brake pad defines a primary pivot axis and is pivotably mounted for frictional engagement with the braking surface. The bias spring serves to urge the contact surface of the brake pad into frictional engagement with the braking surface of the drum.

摘要： A magnetic speed controlling twist grip assembly includes a linear IC, first and second magnets, a stationary member; and a rotary handle turnably connected to the stationary member at an inward end. The linear IC is disposed in the stationary member. The first and second magnets are disposed at the inward end of the handle such that different magnetic poles thereof face respective ones of opposite sides of the linear IC. The magnetic field around the linear IC is changed when position of the magnets relative to the linear IC is adjusted with the user's hand turning the rotary handle, and in turn, electric currents passing through the linear IC is changed. A control device, to which the linear IC is electrically connected, will control electric power supplied from a storage battery to a motor accordingly, thus controlling speed of the motor.

摘要： A brake-shift lever interlock unit (14) includes a pair of coils (24, 26) which are disposed in a coaxial relationship. A plunger (50) is movable in a passage (72) which extends through the coils (24, 26). When the plunger (50) is in a extended position, it is effective to block movement of a force transmitting member (52) connected with a vehicle shift lever (10) Upon actuation of the vehicle ignition switch (18), while the brake switch (20) remains in an unactuated condition, a plunger pull coil (24) is energized to move the plunger (50) from the extended position to the partially retracted position. A cam surface (68) on the plunger (50) then engages the force transmitting member (52) to continue to prevent movement of the vehicle shift lever (10) out of the park position. At this time, the plunger (50) engages a stop member (60). Upon actuation of the vehicle brake (44), a stopper hold coil (26) is de-energized and force applied against the cam surface (68) on the plunger by the force transmitting member (52) is effective to move the plunger (50) to the fully retracted position to enable the force transmitting member (52) to move to a release position.

摘要： A controlled exhaust brake for an engine comprises an exhaust restrictor located in an exhaust system downstream of an exhaust manifold of an engine. An actuator operably associated with the restrictor adjusts the restrictor. A pressure sensor operably associated with the exhaust manifold senses pressure in the exhaust manifold. A controller determines a set pressure in the exhaust manifold correlated with speed of the engine. The controller is in communication with the pressure sensor and the actuator, and causes adjustment of the restrictor in order to achieve and maintain the set pressure in the exhaust manifold.
