ELECTRIFIED VEHICLE PERFORMANCE MODE WITH INTENTIONAL WHEEL SPIN FOR TIRE HEATING
An electrified vehicle includes a controller programmed to implement performance mode control of first and second electric machines and wheel brakes associated with wheels of respective first and second axles to provide a braking force to a first axle while providing torque to the second axle to intentionally spin the tires of the second axle to provide a peelout and associated heating or smoking of the tires to improve traction and provide a visual display of power. The maneuver may be repeated for the first axle by providing torque to the first axle while applying braking force to the second axle. A sequential maneuver that spins tires of the first axle followed by tires of the second axle may be performed by specified manipulation of the brake pedal and accelerator pedal.
REGENERATIVE BRAKING TORQUE CONTROL SYSTEM AND METHOD OF ELECTRIC VEHICLE
A regenerative braking torque control system of an electric vehicle, includes a travel information setting section selects a regenerative braking level in response to a driver’s input and setting at least one driving mode among a plurality of driving modes, an in-vehicle information detector which detects in-vehicle information corresponding to a number and in-vehicle positions of occupants seated on vehicle seats, and a controller which allows driving to be performed according to the regenerative braking level selected by the travel information setting section, the controller transferring motor torque responsiveness according to the number and the in-vehicle positions of the occupants detected by the in-vehicle information detector to a motor controller for driving the vehicle by reflecting the motor torque responsiveness on regenerative braking torque.
Vehicle activation systems and methods for electric vehicles
Methods and systems for activating electric vehicles are provided. One method includes, in response to a first command to activate the vehicle, transitioning the vehicle from an inactive state to a wake state where a controller of the vehicle is activated and the vehicle is prevented from being propelled by an electric motor of the vehicle. The method also includes, in response to receiving a second command to activate the vehicle after receiving the first command, transitioning the vehicle from the wake state to a ready state where the vehicle is permitted to be propelled by the electric motor.
Method for controlling a rotary electrical machine in order to compensate for the torque oscillations of a traction chain of a motor vehicle
A method for controlling a rotating electrical machine of a motor vehicle is disclosed. The motor vehicle includes a thermal drive chain including a heat engine connected to a gearbox by means of a clutch. The electrical machine is integrated in the thermal drive chain or in a drive chain independent of the heat engine. When the clutch is open and the rotating electrical machine operates in motor mode in order to ensure the electrical operation of the motor vehicle, the method includes: generating a setpoint torque corresponding to a desire of the driver to accelerate; determining a pulsed compensation torque for torque oscillations generated by the drive chain; combining the setpoint torque and the previously determined pulsed compensation torque in order to obtain a resulting modified setpoint torque; and applying the resulting modified setpoint torque to the rotating electrical machine.

VEHICLE AND METHOD OF CONTROLLING SPEED LIMIT FOR THE SAME
Disclosed are a vehicle for generating an acceleration profile based on the acceleration cognitive characteristics of the human and a method of controlling the same. The method includes: receiving a manipulation amount of an accelerator pedal and calculating a first torque value, inserting the first torque value to a function that receives force and outputs acceleration feeling, generating a second torque value by inserting an output value of the function into a first filter for stabilizing the output value, generating a target torque value by inputting the second torque value to a second filter for stabilizing the second torque value, and generating a torque command based on the target torque value.
STARTING CONTROL METHOD OF FUEL CELL VEHICLE
A starting control method and system of a fuel cell vehicle are provided. The method includes detecting a cold-running-mode condition including a fuel-cell coolant temperature during stoppage of the vehicle and determining whether the coolant temperature is less than a first set value that is preset in a memory. A vehicle restarting process in the memory is then set using information regarding a vehicle state during the stoppage of the vehicle when the coolant temperature is less than the first set value.
