CONTROL SYSTEM FOR ELECTRIC VEHICLE
A control system for an electric vehicle configured to simulate an engine stall which might occur in conventional vehicles while preventing the simulation of the engine stall in an unfavorable situation. A controller of the control system is configured to: execute an engine stall control to simulate a behavior of the conventional vehicle in a situation where an engine stall occurs by stopping a motor, when a virtual engine speed calculated by a virtual engine speed calculator falls below a predetermined speed; and execute a hold assist control to apply a brake torque to the wheel by the brake device upon execution of the engine stall control.
Torque deration in response traction control events
A method, apparatus, and system are disclosed for incrementally derating a torque applied by a drivetrain in response a number of traction control events detected by a traction control system over a predetermined time period.
METHODS OF OPERATING AN ELECTRIC VEHICLE AND ELECTRIC SNOWMOBILE
A method for operating an electric vehicle has the steps of: determining if at least one of a speed of the vehicle and a speed of an electric motor of the vehicle is zero; in response to the at least one of the speed being zero, determining if a reverse actuator is actuated; in response to the reverse actuator being actuated, starting a timer, then determining if the reverse actuator has been actuated without interruption for a predetermined amount of time; in response to the reverse actuator having been actuated without interruption for the predetermined amount of time, changing an operation mode of the electric motor from one of a forward mode and a reverse mode to another of the forward mode and the reverse mode. An electric snowmobile and other methods for operating an electric vehicle are disclosed.

SAFETY METHOD AND SYSTEM ON VEHICLES WITH TRANSPORT REFRIGERATION
Aspects of the invention are directed towards a system and method for safe decoupling of the external power supply from a vehicle. The technology described herein provides an indication or an alert to the user at an appropriate time and avoids the possible damage to the system. The system comprises an electrical port by which the refrigerator can be connected to an external AC mains supply via an electrical cable when the vehicle is in stationary state. The system further comprises a refrigerator main controller unit (RMU) for controlling the power delivered to the refrigerator in both stationary and driving states of the vehicle. There is a safety system installed for restricting the vehicle from being driven when the electrical port of the system is connected to the AC mains supply via the electrical cable and the refrigerator is powered by the AC mains supply.
Electrified vehicle system and control method of controlling electrified vehicle
An electrified vehicle system includes an electric motor coupled to a drive wheel via a plurality of power transmission components and a control device. The control device is configured to act as: a feedforward control section configured based on a transfer function simulating vibration transmission characteristics of a power transmission system, receiving as an input a required torque of the electric motor from a driver, and outputting a base command torque of the electric motor; a timing estimation section estimating, based on information on the power transmission system, a timing at which a backlash between the plurality of power transmission components is eliminated; and a torque correction section applying, to the base command torque, a correction torque for reducing a vibration generated in the power transmission system due to elimination of the backlash, in response to an arrival of the timing estimated by the timing estimation section.
