Embodiment
Adjust and can alleviate clutch slip to the torque input of clutch.A kind of method adjusting vehicle motor and input the torque of clutch has been shown in Fig. 1.Adjust in a case where and the torque of clutch is inputted: the position of clutch is within the scope of preposition; When first scheduled time, internal clutch remained within the scope of preposition; And the gearbox of vehicle keeps selected gear within second scheduled time.
The method comprises three standards that adjustment torque must meet: standard 1 relates to the position of clutch; Standard 2 relates to the time period that clutch remains on this position; And standard 3 relates to the time period of the selected gear of vehicle gear box maintenance.
Particularly: standard 1 comprises the position of determining clutch and made comparisons in the position of this clutch and preposition scope; Standard 2 comprises determines that clutch remains on the first time period of this position and first time period and first scheduled time made comparisons; And standard 3 comprises the second time period of the selected gear of gearbox maintenance determining vehicle and is made comparisons the second time period and second scheduled time.Selected gear position sensor and/or transmission input shaft sensor can be used to determine the gearbox-gear selected.
According to the result compared, the method provides signal A to input to adjust motor the torque of clutch.Signal A is configured to limit motor and inputs to the torque of clutch.
In the first embodiment of the present invention, when meeting standard 1 to 3, provide signal A to limit the torque from motor to clutch to input, wherein: for standard 1, the position of clutch exceeds preposition time range; For standard 2, first time period was greater than for first scheduled time; And for standard 3, the second time period was greater than for second scheduled time.
