Publication number: 20190381991Abstract: A hybrid powertrain system includes an engine and an electric machine respectively connected to first and second drive axles, with the electric machine decoupled from the engine. The system includes a battery pack and a controller. The controller has slip integrators with a corresponding integrator value for a given one of the drive axles. The integrator values are indicative of an accumulated amount of drive wheel slip over a calibrated duration or window. The integrator values change responsive to axle torque and traction control status signal. The integrator values are added together to derive an integrator sum. Responsive to the integrator sum exceeding a calibrated integrator threshold, the controller executes a control action, including automatically executing a Weather Mode in which energy use of the battery pack is reserved for traction control/propulsion of the vehicle.Type: ApplicationFiled: June 18, 2018Publication date: December 19, 2019Applicant: GM Global Technology Operations LLCInventors: William L.

Publication number: 20190381993Abstract: An apparatus and a method for controlling a motor of an electric vehicle are disclosed. The apparatus receives a driving route for the electric vehicle and divides the driving route into sections. Each of the sections has one of two or more predefined road types. The apparatus calculates a motor control value for each of sections using pieces of past driving-related information of the electric vehicle for each one of the two or more predefined road types, and controls a motor of the electric vehicle based on the calculated motor control value. The electric vehicle may be an autonomous vehicle. In this case, the autonomous vehicle may be operated with an arbitrary artificial intelligence (AI) module, a drone, an unmanned aerial vehicle, a robot, an augmented reality (AR) module, a virtual reality (VR) module, a fifth generation (5G) mobile communication apparatus, or the like.Type: ApplicationFiled: August 30, 2019Publication date: December 19, 2019Inventors: Jingu PARK, Gyujin KIM, Manwoo KIM, Seunggyu CHOI

Publication number: 20190381995Abstract: Methods and systems are described for conserving energy used by an energy consuming device. In certain embodiments, an energy conservation system can be configured to deliver energy to the energy consuming device for a period, followed by a period where energy delivery is dampened and/or cut. By cycling the delivery of energy in this fashion, the energy conservation can achieve a pulsed efficiency.Type: ApplicationFiled: June 21, 2019Publication date: December 19, 2019Inventors: Jeffrey N.

Publication number: 20190381996Abstract: A control apparatus for a vehicle controls a hybrid vehicle including a drive motor and an engine, both of which are linked to a driving wheel. The control apparatus includes: a regenerative controller; a fuel injection controller; a clutch controller; a condition satisfaction determiner; and a delay controller. The regenerative controller regeneratively drives the drive motor at the time of decelerating the hybrid vehicle. The fuel injection controller stops a fuel injection at the time of decelerating the hybrid vehicle. The clutch controller releases a clutch that switches a power transmission on and off between the engine and the driving wheel at the time of a regenerative driving by the regenerative controller. The condition satisfaction determiner determines whether execution conditions of diagnoses performed in a fuel cut state in which the clutch is engaged and the fuel injection is stopped are all satisfied.Type: ApplicationFiled: May 14, 2019Publication date: December 19, 2019Applicant: SUBARU CORPORATIONInventors: Atsushi KANEKO, Masahiro ONO
