    Abstract: A system for providing a movement assistance to an electric cycle is provided. The system includes circuitry communicatively coupled to an electronically-actuated driving mechanism and a sensor system of the electric cycle. The circuitry receives sensor information associated with the electric cycle through the sensor system and determines an inclination of the electric cycle with respect to an inclination-reference based on the received sensor information. The circuitry further determines occupancy information associated with a seat of the electric cycle based on the received sensor information. Based on the determined inclination and the determined occupancy information, the circuitry controls the electronically-actuated driving mechanism to drive at least one wheel of the electric cycle.

  • Patent number: 11214273
    Abstract: In a self-driving autonomous vehicle, a controller architecture includes multiple processors within the same box. Each processor monitors the others and takes appropriate safe action when needed. Some processors may run dormant or low priority redundant functions that become active when another processor is detected to have failed. The processors are independently powered and independently execute redundant algorithms from sensor data processing to actuation commands using different hardware capabilities (GPUs, processing cores, different input signals, etc.). Intentional hardware and software diversity improves fault tolerance. The resulting fault-tolerant/fail-operational system meets ISO26262 ASIL D specifications based on a single electronic controller unit platform that can be used for self-driving vehicles.

  • Patent number: 11167643
    Abstract: Presented are intelligent vehicles and control logic for provisioning comprehensive tow features, methods for manufacturing/operating such vehicles, and electric-drive vehicles with tow features for protecting the vehicle's powertrain and electrical components during towing. A method for controlling operation of an electric-drive vehicle includes a vehicle controller verifying initiation of a towing operation for the vehicle, and responsively determining if there is a drive system failure preventing the vehicle's traction motor from electrically connecting with its traction battery pack. If there is no drive system failure, the controller determines if the speed of the traction motor during towing exceeds a calibrated base speed; if so, the controller commands a power inverter to electrically connect the traction motor to the traction battery pack.

    Abstract: A hybrid electric powertrain for a vehicle includes an engine, electric machine, torque converter having a pump, turbine, and torque converter clutch (“TCC”) configured, when applied, to lock the pump to the turbine, a one-way engine disconnect clutch connected to the turbine, a transmission, and a controller. A transmission input shaft directly couples to the electric machine, and is selectively coupled to the engine via the disconnect clutch. An output shaft is connectable to road wheels of the vehicle. The controller, in response to an engine-off request, determines turbine and pump speeds of the turbine and pump, respectively, registers that the engine is in an engine-off state when the pump speed is less than the turbine speed, and executes an electric vehicle (“EV”) mode shift using machine torque from the electric machine when the pump speed is zero during the engine-off state.

  • Patent number: 11161487
    Abstract: A system for controlling wheel brakes in a first vehicle platooning with a second vehicle includes a transceiver in the first vehicle that receives a brake command from the second vehicle to apply a wheel brake in the first vehicle. A controller in the first vehicle generates, responsive to the brake command, a first set of control signals that control delivery of fluid pressure to the wheel brake and implement a braking event. The controller may further detect a wheel slip condition indicative of slip in a wheel of the first vehicle during the braking event and generate, when the condition occurs, a second set of control signals to control delivery of fluid pressure to the wheel brake. The control signals are generated in accordance with braking profiles that differ from braking profiles used by the controller during braking events occurring in the absence of the brake command.
