摘要： Linkage is disclosed for adjusting the position of a diesel engine injection pump control rack in dependence on the position of the driver's accelerator pedal and also on a system for automatically maintaining the vehicle speed at a desired value. The injection pump rack is positioned by means of a pneumatic piston-cylinder assembly and connecting linkage. The pressure in the piston-cylinder assembly is adjusted by means of a driver-controlled valve in a supply line from a pressure source, and this valve is adjusted by the driver's accelerator pedal. A normally open valve is also connected in the pressure circuit and a normally closed exhaust valve is provided. When the automatic speed control system is in operation, the driver fully opens the driver-controlled valve (by fully depressing his foot pedal) and the automatic system adjusts the other valves to hold the speed at the desired value. When the driver releases his foot pedal, the driver-controlled valve shuts, preventing the automatic speed control having any further effect on engine power.

摘要： An improved input circuit for an electronic vehicle speed control unit is disclosed. An ignition current sensor coil is adapted to have a voltage differential signal induced therein each time an ignition pulse is generated by the vehicle engine. Electrical noise signals generated by the vehicle engine appear as common mode signals across the ignition current sensor coil. The ignition current sensor coil is connected at each end to a capacitor, both of which are connected to ground potential. The ends of the ignition current sensor coil are further connected to the inputs of a differential amplifier. The capacitors appear in a series loop with the ignition current sensor coil for the differential voltage signals and, consequently, provide tuning for inductance. However, the capacitors appear in parallel with one another to ground potential with respect to the common mode noise signals, thereby providing high frequency noise rejection for the input circuit. The differential amplifier further rejects the common mode noise signal applied to the inputs thereof.

摘要： The invention relates to an actuator device for a motor vehicle speed-responsive system, the device being operable to actuate the throttle valve or the like of the internal combustion engine of the vehicle. The actuator device comprises a bellows device defining a first chamber partly bounded by a movable wall and a fixed wall, and communicating with two further chambers defined by associated housings carried by the said fixed wall. One of the further chambers contains a first electro-magnetic control valve fed by a D.C. voltage, and operable to control an orifice through which the first chamber communicates with atmosphere. The other of the further chambers contains a second electro-magnetic control valve fed both by said D.C. voltage and by a pulsed voltage, and operable to control both an orifice through which the first chamber communicates with atmosphere and an orifice through which the first chamber communicates with a source of gas at sub-atmospheric pressure.

摘要： An automatic braking system for a vehicle including an automatic command system giving a command including at least one braking signal of a level in response to the need for braking, a fluid pressure source, a braking device having an input member which is manually actuatable, and a device for actuating the input member by applying thereto a fluid pressure from the pressure source in response to the level of the braking signal. An automatic braking may thus be performed while permitting manual braking to be simultaneously effected.
