  • Patent number: 11554058
    Abstract: A mobility scooter control system includes a remote control console having a wireless transmitter and switches. A status detection circuit is integrated with the switches. The status detection circuit emits a pulse on a regular cycle. After the pulse passes the respective switch following a change in state of the switch, a wireless transmission is sent. A controller is electronically connected to a motor. The control system has a regular operation mode in which direction of movement and speed limit functions are responsive to instructions inputted to the controller, and, in the absence of user instruction, the controller does not instruct movement of the motor. The control system has a Sabbath operation mode in which the direction of movement and speed limit functions are responsive only to signals from the wireless transmitter, and, in the absence of user instruction, the controller instructs the motor to continuously cycle backward and forward.

  • Patent number: 11548384
    Abstract: When evacuation travel is performed using only a drive power from one drive power source of an engine and a rotary machine, a drive power distribution device is prohibited from switching to a four-wheel-drive state and thus evacuation travel is performed in a two-wheel-drive state in which a loss in a power transmission device is relatively small. Accordingly, in a four-wheel-drive vehicle, it is possible to increase an evacuation-travelable distance when evacuation travel is performed using only the drive power from one drive power source of the engine and the rotary machine.

  • Patent number: 11541741
    Abstract: The present invention relates to the field of electromechanical equipment for use in the vehicular field. More specifically, it relates to a selector, doser and transmitter of torque and power between one or more engines and one or more final transmission shafts. Applied for example on a vehicle without a gearbox, the new mechanism allows for selection of the ratio between the speed of rotation of one or more driving sources (such as an internal combustion engine drive shaft) and the final transmission shaft. In a preferred configuration, this selection is controlled electronically, managing the broad scope of possibilities provided by the mechanical configuration of this mechanism to dose the torque and power and regulate the rpm of the driving sources, in a hybrid motorization system.

  • Patent number: 11441670
    Abstract: Because an EOP starts operating from when a decrease in discharge flow rate of an MOP is predicted or detected, a PL actual pressure that should be obtained with a PL command pressure set to a value for a required transmission torque is more easily maintained even when the discharge flow rate of the MOP becomes insufficient. After a lapse of a predetermined period of time from the start of operation of the EOP, the PL command pressure is temporarily set to a value higher than the value for the required transmission torque, and a regulator valve is controlled to operate to close a drain port. Therefore, the operation of the EOP in a high PL actual pressure is reduced, and a delay in response of a pressure regulating operation of the regulator valve in the process of reduction of the discharge flow rate of the MOP is reduced.

  • Patent number: 11325577
    Abstract: An on-board controller executes a torque reduction process that reduces torque generated by an electric motor when a brake pedal of a vehicle is depressed and the vehicle is stopped during motor creep driving. When a start request for an internal combustion engine is issued, the on-board controller executes an engine start process that sets a clutch mechanism to an engagement state, which engages an output shaft of the internal combustion engine with an output shaft of the electric motor, and drives the electric motor to perform cranking. When a state in which the clutch mechanism is maintained immediately before the engagement state is defined as an engagement preparation state, the on-board controller executes a preparation process that applies hydraulic pressure to the clutch mechanism during execution of the torque reduction process so that the clutch mechanism is set to the engagement preparation state.

  • Patent number: 10947921
    Abstract: Methods and systems are provided for diagnosing whether one or more intake air oxygen sensors positioned in an intake of an engine of a vehicle, are functioning as desired. In one example, a method comprises injecting fuel into one or more cylinders of the engine without combustion, routing un-combusted hydrocarbons from the one or more cylinders to the intake via a crankcase ventilation system, and indicating whether the one or more intake air oxygen sensors are functioning as desired based on a response of the one or more intake air oxygen sensors. In this way, the one or more intake air oxygen sensors may be periodically diagnosed which may improve engine operation, and reduce engine degradation, particularly with regard to hybrid electric vehicles with limited engine run-time.
