  • Electromechanical controller for vehicles having a main processing module and a safety processing module
    Patent number: 11535266
    Abstract: A driving system for a vehicle includes one or more sensors, a controller, an actuator, and a safety shut down switch. The controller includes a main processing circuit, a main processing module, an actuator drive, a safety processing circuit, a safety processing module, and a safety shutdown switch. The safety processing module is independent of the main processing module, and the safety processing module is configured to perform one or more safety functions.

  • Hydraulic drive system with exiting from pumping and motoring
    Patent number: 7779628
    Abstract: A hydraulic drive system for storing and releasing hydraulic fluid includes a high pressure storage device, a low pressure storage device, and a pump-motor operating at a range of pump-motor speeds for converting between hydraulic energy and mechanical energy. The pump-motor is disposed between the high pressure device and the low pressure device. In normal operation, the hydraulic drive system enters a motoring mode where hydraulic energy is released from the high pressure storage device and converted to mechanical energy using the pump-motor. It also enters a pumping mode where mechanical energy is converted into hydraulic energy. A neutral state exists where hydraulic energy is neither stored nor released from the high pressure storage device. An approach for exiting either the motoring mode or the pumping mode promotes efficiency within the hydraulic drive system.
