Latest Patents
One of his latest patents involves intelligent vehicles and control logic for managing faults in dual-independent drive unit axle powertrains. This patent presents control systems designed to operate dual-independent drive unit (DIDU) powertrains. It includes methods for making and operating such systems, as well as electric-drive vehicles equipped with fault management and mitigation for DIDU axles. The method of operating a motor vehicle with a DIDU axle involves monitoring first and second drive units that independently drive respective road wheels. A vehicle controller receives indications of fault conditions and determines the fault type, as well as the vehicle's current speed. This information is used to set torque limits for each drive unit based on the fault type and speed, ensuring safe operation.
Another significant patent focuses on a vehicle monitoring strategy for detecting unintended acceleration during speed control. This method determines external forces acting on the vehicle and calculates desired acceleration based on measured vehicle speed. It includes filtering speed signals and using an inertial measurement unit (IMU) to measure actual acceleration. The method calculates an acceleration delta value to detect unintended acceleration during closed-loop
