Abstract
A motor vehicle (201) has an engine (201), a clutch (203), and a transmission (204) with a shift lever (230). A sensor (232) arranged at the shift lever (230) detects movements of the shift lever or forces applied to the shift lever. When the sensor (232) detects a movement or force, the activity is interpreted as a signal that the driver intends to shift gear. A detector system of the motor vehicle detects conditions such as the presence and magnitude of a mechanical play which can affect the process of shifting gears in the transmission (204).
Claims153
A motor vehicle, comprising a power train with:
- at least one drive source to generate at least one mechanical drive quantity;
- at least one output device to produce at least one mechanical output quantity;
- at least one transmission device arranged in the power train between the at least one drive source and the at least one output device, to convert a transmission input quantity into a transmission output quantity, the transmission device being operable to shift from one to another of at least two different gear levels that are distinguished by different transmission ratios between respective magnitudes of the transmission input quantity and the transmission output quantity;
- at least one transmission-actuator device to actuate the shifting from one to another of the at least two gear levels;
- at least one intent-to-shift detecting device to detect when a gear shift is about to occur;
- and
- at least one detector system to detect the presence of a performance-affecting condition having an influence on the shifting of the transmission device.
A method of detecting an intent to shift of a driver in a vehicle with at least one transmission device and at least one shifting device, said method comprising the step of determining the intent to shift in accordance with a prescribed detection characteristic, wherein the detection characteristic gives at least partial weight to an amount of play existing in at least one of the transmission device and the shifting device.
