Abstract: A driver assistance system may be a vehicle control system configured to perform a driver assistance operation, such as implementing cruise control or performing an automated driving control operation. The control system may be configured to perform a driver assistance operation which includes at least one step which conserves energy stored in at least one battery. The control system may conserve energy by controlling a speed or following distance of a vehicle based on road parameter, such as an uphill grade or downhill grade.

Abstract: A split-flow coolant system is provided. The split-flow coolant system may include a single inlet and multiple coolant distribution channels arranged inside a housing, or cooling plate, of the inverter. The coolant distribution channels may include a coolant chamber connected to the inlet and a coolant path running adjacent to various portions of the inverter. The coolant chamber splits into two separate coolant paths in the inverter housing, or cooling plate, that are then diverted to each of the motors. A first coolant path is diverted to the first motor where the coolant path is arranged to cool the first motor and a second coolant path is diverted to the second motor to cool the second motor. The separate coolant paths may connect to a common outlet at the end of the cooling path for the motors.

Abstract: A smart braking system for a vehicle is provided. The smart braking system selectively activates a braking system of the vehicle when the smart braking system detects a scenario in which it is likely that a constant vehicle speed, rather than an increasing vehicle speed, would be desired by a driver. In one example, a driver releases an accelerator while the vehicle is on a decline but the vehicle accelerates anyway. In this instance, the smart braking system records the speed of the vehicle when the accelerator is released and applies the braking system to maintain the speed of the vehicle at the recorded speed while the vehicle is on the decline. The smart braking system stops activating the braking system upon detecting that braking is no longer needed to slow down the vehicle.

Abstract: Described herein is a method and sanity monitoring system for power modules that detect abnormal conditions with respect to transistors in the power modules. A sanity monitor is added to each transistor. The sanity monitor can include a sensor that detects voltage, current, temperature, magnetic fields or similar parameters that indicate a health of a transistor. A failure handling device receives measurements from the sanity monitors and determines whether the measured parameters are within expected ranges for the transistors. If an abnormality is detected, the failure handling device performs a corrective action. For example, the failure handing device can reduce the overall current in a power stage to prevent remaining transistors from failing. The failure handling device additionally informs the driver, (e.g., via an input/output (I/O device), of the problem, indicating that the driver should bring the car to service.

Abstract: Systems of an electrical vehicle and the operations thereof are provided. Embodiments include an electric vehicle, rechargeable electric vehicle, and/or hybrid-electric vehicle and associated systems. The electric vehicle includes redundant vehicle control systems that monitor each other to prevent a dangerous reduction or change in torque to the electric motor(s). By monitoring each other, the redundant VCUs can ensure that a failure of the opposite VCU does not endanger the vehicle and may be shut down when the opposite VCU when the VCU's behavior is outside acceptable operating circumstances.

Abstract: A speed control system includes features which allow for control of a target speed through use of an acceleration pedal and a brake pedal. The control system includes a drivetrain, a braking system, and a plurality of traction devices configured to accelerate and decelerate the vehicle based on input from the drivetrain and braking system. The control system further includes the acceleration pedal and brake pedal configured to be operated by a driver. The control system also includes a controller and one or more sensors. The controller is electronically connected to the drivetrain, the braking system, the acceleration pedal, the brake pedal, and the one or more sensors. The controller is configured to store a target speed and adjust the target speed based on input from the acceleration pedal, the brake pedal, and the one or more sensors.

Abstract: In incremental detectors, measurement signals thereof are first corrected in graduation-specific fashion with respect to amplitude offsets, and phase displacement, and a rough angle is determined. The residual error of the rough angle is fine-corrected via rough-angle-specific, graduation-independent rough angle correction values and a position signal is determined in this way. The correction values for amplitudes offsets, and phase displacement are determined using regression, and the rough angle correction values are determined using high-precision reference angle measurements.
