Drive control system for vehicle

In a drive control system for a vehicle configured to cause the vehicle to travel in a limp-home mode when a malfunction occurs in a selectable one-way clutch, when it is determined that a malfunction occurs in the SOWC, the cause of the malfunction is specified as one of a plate-open failure of a selector plate that is unintentionally placed in an open state, and a sensor failure. In the case of the plate-open failure, a first limp-home traveling mode is carried out in which the vehicle travels in the limp-home mode while keeping the SOWC in a negative rotational speed range. In the case of the sensor failure, a second limp-home traveling mode is carried out in which the vehicle travels in the limp-home mode while the SOWC is placed in the non-engaged state.

System and method for preventing clutch burst

A control system for a vehicle having a manual transmission system includes an anti-lock braking system configured to apply brakes of the vehicle, a clutch pedal configured to control engagement/disengagement of a clutch disc with a pressure plate of the manual transmission system, and a controller configured to perform a clutch burst prevention technique when the clutch pedal is depressed such that the clutch disc is disengaged from the pressure plate, the clutch burst prevention technique comprising: obtaining a set of operating parameters of the vehicle, determining a vehicle speed threshold based on the set of operating parameters, the vehicle speed threshold being a speed of the vehicle at which clutch burst begins to occur, and when the vehicle speed is within a first threshold amount from the vehicle speed threshold, decreasing the vehicle speed by commanding the anti-lock braking system to apply the vehicle brakes.

Rotor for vehicle pedal with contacting sensor

A vehicle pedal with a contacting sensor that comprises a pedal arm coupled to and rotatable relative to a pedal housing. A rotor includes a first end coupled to the pedal arm and an opposed end with contactors abutting and adapted to slide against a resistive element in response to the rotation of the pedal arm. A head on the rotor includes means for preventing the over-deflection of the contactors. In one embodiment, the means for preventing the over-deflection of the contactors comprises an extension on the head of the rotor that defines a stop limiting the deflection of the contactors. In another embodiment, the means for preventing the over-deflection of the contactors comprises the combination of a tab on the head of the rotor and a wall in the interior of the pedal housing. The tab abuts against the wall and prevents the movement of the rotor in the direction of the resistive element.

Method for detecting and mitigating excessive clutch disc wear in manual transmissions

A method for detecting and mitigating excessive clutch disc wear for a manual transmission includes determining if a clutch pedal position is depressed greater than or equal to a first predetermined pedal position threshold and if the vehicle speed is less than or equal to a predetermined vehicle speed threshold. The method further includes determining if the clutch pedal position is depressed greater than or equal to a second predetermined pedal position threshold when the clutch pedal position is depressed less than the first predetermined pedal position threshold. The method still further includes calculating a clutch disc heat flux value and a clutch disc surface temperature. The method further includes displaying an alert/warning and a remedial action message to a vehicle operator when the clutch disc surface temperature is greater than or equal to a predetermined surface temperature threshold.

10124786 · 2018-11-13 · ·

A method for determining a measuring point of a hybrid decoupler of a hybrid vehicle, which is operated by a hydrostatic clutch actuator, with the hybrid decoupler coupling or decoupling an internal combustion engine and an electro-traction drive. The measuring point is determined by a slow operation of the hybrid decoupler, starting from a position of the hybrid decoupler which it assumes in the idle state, when a defined increase in torque is detected at the electro-traction drive. In the method, the term for measuring adaption is considerably shortened, and the measuring point is adapted at a running internal combustion engine and a stationary electro-traction drive.

SYSTEM, METHOD, AND APPARATUS FOR OPERATING A HIGH EFFICIENCY, HIGH OUTPUT TRANSMISSION

A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.
