Abstract: Apparatus for a vehicle is provided such that the throttle pedal can act as a virtual footrest. The apparatus comprises a pedal adapted to be depressed by a driver and a restriction mechanism adapted to restrict the displacement of the pedal. The apparatus also comprises a visual sign which enters a first illuminated state in response to activation of the footrest mode. The visual sign remains in the first illuminated state whilst the restriction mechanism retains the pedal in the footrest position, and is extinguished when footrest mode or cruise control is cancelled. The visual sign enters a second illuminated state when the pedal is subjected to a force greater than a first threshold value, so as to push the pedal past through the footrest position whilst in the footrest mode.

Abstract: A start safety circuit arrangement is incorporated into a work apparatus having an internal combustion engine. Combustion air and fuel are supplied to the combustion chamber by a control unit for the engine operation. The fuel/air mixture in the combustion chamber is ignited by an ignition plug. An operating mode selector has a start position for enriching the fuel/air mixture. A safety brake device in an operating mode brakes the work tool. A start position sensor is arranged on the operating mode selector and a brake position sensor is associated with the safety brake device. The status signal of the brake position sensor and the status signal of the start position sensor are combined to cause the control unit to disable the engine operation if the operating mode selector is in start position (III) and the safety brake device is in its standby mode (B).

Abstract: A method and system for managing cruise control in a machine provide for maintaining a speed of the machine at a target speed in the absence of an acceleration or deceleration command from an operator of the machine. When a deceleration command is received from the operator of the machine the machine is slowed below the target speed while the deceleration command is received and is returned to the target speed when the deceleration command is no longer received.

Abstract: Excursion prevention methods and systems may include transmitting a speed signal from the vehicle speed sensor to the electronic control unit; transmitting a transmission signal from the transmission sensor to the electronic control unit; transmitting an accelerator pedal signal from the accelerator sensor to the electronic control unit; transmitting a brake pedal signal from the brake sensor to the electronic control unit; executing a machine readable control logic with the electronic control unit to determine if an excursion condition is present based on the speed of the vehicle, the status of the transmission, the application of the accelerator pedal of the vehicle, and the application of the brake pedal of the vehicle; and, transmitting an alert signal from the electronic control unit when the excursion condition is present.

Abstract: A method for starting a motor vehicle on a downhill route from an idle state includes the steps of maintaining a sufficient brake force to hold the motor vehicle in the idle state, even if brake actuation by the driver is withdrawn; detecting a wish by the driver to drive off; reducing, independently of the driver, the brake force which is maintained independently of the driver, in such a way that the resulting movement of the motor vehicle follows a preset course.

Abstract: A cruise control system for motor vehicles controls the vehicle speed to a preset desired speed. The cruise control system includes an operating unit for switching the cruise control on and off, an accelerator pedal, normally present in the vehicle, for activating the cruise control and for presetting the desired speed, and a brake pedal, also normally present in the vehicle, for interrupting the active cruise control. The operating unit is configured as a single operating element, during whose actuation the cruise control is switched on or off as a function of the actual operating condition of the cruise control system.

Abstract: A drive control system for an electric vehicle and a method of drive control of the electric vehicle. The drive control system for the electric vehicle includes a drive motor target torque calculation processing device for calculating a drive motor target torque representing a target torque of a drive motor; and a drive motor target torque restriction processing device that judges whether or not a parking mechanism is in operation and, if the parking mechanism is in operation, restricts variations in the drive motor target torque.

Abstract: By calculating energy used by friction brake equipment, the amount of friction brake shoe/pad wear is monitored. As amount of energy supplied reaches a percentage of the friction brake shoe/pad energy design limit, and indication for inspection is provided. If the supplied friction energy continues to increase the brake material must be replaced. The software logic limits are tunable for custom configuration by maintainace personnel. This invention measures amount of friction effort supplied with respect to time and distance in a software controller brake system and allows the software to determine when the friction brake material must be replaced on actual data and avoids costly damage from braking with worn out shoes/pads. This invention annunciates through the software when the friction material requires inspection and replacement and provides software logic to indicate remaining material thickness.

Abstract: A motorcycle having a speed control rotary throttle grip and a pivoted brake lever both mounted on a steering handlebar, is provided with a split clamp ring surrounding the throttle grip and movable to releasably clamp the throttle grip against rotation from a preset position of cruising speed. A catch pin supported by one section of the split clamp ring is movable with the other section of the clamp ring to releasably secure the sections together. The catch pin is movable either manually by physical force or automatically by movement of the brake lever during braking of the motorcycle speed. Manual force may be applied to move a clamp lever, while automatic operation is achieved by movement of the brake lever into engagement with the clamp lever.

Abstract: A control system for an automatic transmission includes a torque converter which hydraulically transmits rotation of the driving power source to the speed change gear unit, a first friction engagement element, a second friction engagement element, a third friction engagement element, a vehicle stopping detecting mechanism for detecting a vehicle stopped condition when a forward driving range is selected, a vehicle weight detector, and a controller. The controller controls the disengagement of the first and second friction engagement elements and the engagement of the third friction engagement element with an engaging force in response to the vehicle weight when the vehicle stopped condition is detected while the forward driving range is selected.

Abstract: A method for improving efficiency and reducing emissions of an internal combustion engine. Variable displacement engine capabilities are achieved by disabling engine valves during load changes and constant load operations. Active cylinders may be operated at minimum BSFC by intermittently disabling other cylinders to provide the desired net torque. Disabling is begun by early closing of the intake valve to provide a vacuum at BDC which will result in no net gas flow across the piston rings, and minimum loss of compression energy in the disabled cylinder; this saving in engine friction losses is significant with multiple disablements.

Abstract: A method and apparatus for improving efficiency and reducing emissions of an internal combustion engine coupled to an inertial load. An apparatus is provided for controlling the energy exchange between engine and load so that the maximum conversion efficiency is obtained for both directions of energy flow. Valve controls make the engine a variable displacement expander or compressor so that kinetic energy received from the load by the engine may be stored as compressed air and returned to the load by the engine. These controls eliminate all fuel consumption and emissions when power is not required by the load, and utilize the stored energy in conventional engine operation.
