An electronic vehicle clutch pedal comprising a pedal housing and a pedal arm coupled to and rotatable relative to the housing and including a distal drum rotatable relative to the pedal housing and defining a contact surface including at plurality of surface segments with different slopes. A force lever is pivotable about the pedal housing and has a first end abutted against the contact surface on the drum of the pedal arm. A compressible member has a first end abutted against a lower surface of the pedal arm and a second end abutted against a second end of the force lever. The pedal arm is rotatable about the pedal housing to cause the pivoting of the force lever relative to the pedal housing and cause the first end of the compressible member to exert a variable force against the pedal arm.

Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods provide a way of prepositioning an engine to improve a range of driveline disconnect clutch transfer function adaptation. In one example, an engine is positioned at a location where its torque to turn exceeds a threshold torque.

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.

A transmission control system of an electric vehicle includes a motor configured to generate drive torque; a transmission configured to perform multi-stage shifting using a dog clutch in a restraint relationship with a one-way clutch configured to transmit forward power of the motor; a speed sensor configured to measure a rotation speed on an output side of the transmission; a motor control unit configured to control the drive torque from the motor according to a driver's accelerator position signal (APS) value; and a vehicle control unit configured to control the multi-stage shifting of the transmission according to a torque command based on the APS value, and to perform clutch alignment control by moving up a sleeve in a reverse direction to contact a hub through a reverse rotation operation of gear teeth by applying reverse rotation torque of predetermined drive force through the motor in a pre-engagement state of the dog clutch.

A hybrid power system comprises an engine, a motor, an electromagnetic clutch, an electromagnetic clutch controller and a power supply system. The power supply system comprises: a low-voltage battery, a standby power supply system and a switching circuit. The electromagnetic clutch is used to control connection of the motor. A control method comprises: monitoring whether a voltage of the low-voltage battery is lower than a target value, and judging whether the low-voltage battery fails; using the switching circuit to switch to the standby power supply system to supply power to the electromagnetic clutch and the electromagnetic clutch controller; using the electromagnetic clutch controller to judge an engaged or disengaged state of the electromagnetic clutch; and further controlling the electromagnetic clutch according to the engaged or disengaged state. When the low-voltage battery power supply fails, the switching circuit switches to the standby power supply system to supply power.

An engine starting system for hybrid vehicle is provided. The engine starting system is applied to a hybrid vehicle in which a friction clutch is disposed between an engine and a power distribution device. In order to reduce gear noise and vibrations, a second motor establishes a cancel torque to cancel a reaction torque acting on an axle when starting the engine. The engine starting system is configured to increase the torque of the second motor in a direction of a drive torque rotating the axle, when starting the engine while bringing the friction clutch into engagement in a slipping manner.

A mode transition control device a hybrid vehicle has a transmission control unit that prevents a second power generation system from overheating while traveling in a series HEV mode. When a battery is at a power generation request threshold value or lower, the vehicle travels in a series HEV mode, in which the first electric motor is utilized as a drive source and receives electrical power from the second motor/generator and the battery. The transmission control unit controls the traveling mode to transition from the series HEV mode to a parallel HEV mode when the vehicle speed has reached a switchover vehicle speed. When a temperature rise of the second power generation system is predicted while traveling in the series HEV mode, the transmission control unit changes the switchover vehicle speed to a slower switchover vehicle speed that was used prior to a determination of the temperature rise.

A system and method for releasing baulking of a transmission gear of a hybrid vehicle are provided. The method includes comparing a stroke of a gear actuator with a first target value while increasing the stroke of the gear actuator when gear shifting is requested. Additionally, the method includes detecting whether the vehicle is in a stop state, in response to determining that the stroke of the gear actuator is less than a first target value. A motor torque is then increased in response to determining that the vehicle is in a stop state and the stroke of the clutch actuator is increased to be a second target value.

Systems and methods are provided for actuating a clutch of a manual transmission of a vehicle comprising. An automatic emergency braking (AEB) system is configured to automatically initiate an AEB event and a brake controller is configured to automatically actuate a braking system of the vehicle. A powertrain controller in is configured to monitor vehicle parameters and determine when an engine of the vehicle is nearing stall. A clutch control module is configured to actuate a clutch hydraulic master cylinder and actuate the clutch. A vehicle sensor network is configured to detect objects surrounding the vehicle. The AEB system is configured to initiate the AEB event based on detected objects surrounding the vehicle and, when the AEB event is initiated, instruct the brake controller to automatically actuate the braking system and instruct the clutch control module to actuate the clutch when the vehicle is nearing stall

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.
