A vehicle system and method for remote start operation in the vehicle system are provided. The method includes responsive to receiving a remote start request and while the vehicle is stationary, automatically engaging a wheel-arresting device coupled to a wheel in the vehicle. The method also includes when an electronically actuated clutch is automatically disengaged and subsequent to the automatic engagement of the wheel-arresting device, implementing remote start operation in an engine, where the wheel-arresting device is distinct from a secondary vehicle brake.

Vehicle system and method for remote start operation

A vehicle includes an powerplant, a manual transmission, and a clutch. A vehicle controller is programmed to automatically control operation of the clutch allowing the driver to shift gears by just operating the gear shifter. The vehicle also includes an input allowing the driver to override the controller and operate the clutch. The input is located on the gear shifter and is in electric communication with the controller. The controller is programmed to, inter alia, command the clutch to reduce clutch capacity responsive to receiving a signal from the sensor indicating grasping of the shifter.

A braking systemfor use with an electric vehicleincluding an electric motor/generator assembly, and a conventional electrical energy storage device. Motor/generatorselectively drives wheelsof vehicle. The braking systemincludes a motor control modulewhich is communicatively coupled to motor/generatorand which selectively causes motor/generatorto provide a regenerative braking function at wheelsof vehicle. Braking systemfurther includes an antiskid braking system which selectively provides friction braking at wheelsandof vehicle. The braking systemis effective to detect antiskid braking events at each of the wheels, to selectively provide an antiskid braking function at each of wheelswhere the antiskid braking events are detected, and to selectively disable the regenerative braking function only when an antiskid braking event is detected at either of wheels

System and method for regenerative and antiskid braking within an electric vehicle

In an electric or hybrid electric vehicle, a voltage monitor ( ) is directly coupled to a traction motor ( ) and/or generator motor ( ) to detect a permanent magnet induced voltage within the motor at a predetermined speed and no load condition. A controller ( ) compares the detected permanent magnet induced voltage with an expected reference voltage that represents an expected permanent magnet induced voltage at full magnetization and the predetermined speed. The comparison includes identifying points of synchronization and using those points to determine a difference in the detected permanent magnet induced voltage that is caused by a faulty component.

Detection of demagnetization in a motor in an electric or partially electric motor vehicle

In an electric or hybrid electric vehicle, a voltage monitor ( ) is directly coupled to a traction motor ( ) and/or generator motor ( ) to detect a permanent magnet induced voltage within the motor at a predetermined speed and no load condition ( ). A controller ( ) compares the detected permanent magnet induced voltage with an expected reference voltage that represents an expected permanent magnet induced voltage at full magnetization and the predetermined speed ( ). The controller produces an indication of magnetization based on the reference voltage, the detected permanent magnet induced voltage, and the predetermined speed. If the indication of magnetism reaches a predetermined threshold, the motor is made inoperable and/or a current to the motor is limited to prevent damage to components ( ). Preferably, a user of the vehicle is made aware of these actions by an audible and/or visual indicator ( ). If available, another source of motive power is substituted for the motor that is made inoperable ( ).

Adaptive demagnetization compensation for a motor in an electric or partially electric motor vehicle

A vehicle brake systems ( ) is provided which compensates for brake pedal feel variation to provide enhanced braking feel. The brake system ( ) includes a brake pedal ( ), a wheel sensor ( ), and a database ( ) for storing target accelerations and torque to pressure parameters. The brake systems ( ) may employ a friction brakes ( ) and regenerative brakes ( ). The brake system further includes a controllers ( ) for controlling the amount of braking, including the friction brake actuator ( ). The controller ( ) determines brake acceleration caused by braking torque and determines a target acceleration based on the driver commanded input. The controller ( ) also determines a brake acceleration error as the difference between the target acceleration and the brake acceleration. The controller adjusts the torque-related parameter to reduce the brake acceleration error by adjusting the braking torque generated by the friction brake actuator to compensate for brake torque variation.

A method and system that responds to non-propulsive needs of a hybrid vehicle by setting at least two thresholds related to engine support: one threshold to keep a running engine ON and a another threshold to turn the engine ON from an OFF state.

A system or method for compensating for low vacuum levels in a brake-by-wire system includes continually monitoring the level of vacuum in a vacuum booster. The state or condition of the vacuum source is also monitored to determine whether it is on or off. When the vacuum source is off, the level of vacuum is measured to determine whether it is at or below a critical level. If the level of vacuum is critically low, the vacuum source is turned on. If the vacuum level is not critically low, the hydraulic boost gain is modified in order to provide more braking pressure in response to brake force exerted at the brake pedal.

Deceleration and compensation for low vacuum levels in a brake-by-wire braking system

A method is presented for controlling fuel tank pressure in an internal combustion engine. The engine, the fuel tank and the carbon canister are connected in a three-way connection. The engine can be selectively isolated by a purge control valve, and the fuel tank can be selectively isolated by a fuel tank control valve. The operation of both valves is coordinated by an electronic engine controller. By isolating the fuel tank during the carbon canister purge, better estimate of the fuel fraction flowing into the engine can be achieved, thereby improving fuel economy.

Fuel tank pressure control system

A method is presented for controlling fuel tank pressure in an internal combustion engine. The engine, the fuel tank and the carbon canister are connected in a three-way connection. The engine can be selectively isolated by a purge control valve, and the fuel tank can be selectively isolated by a fuel tank control valve. The operation of both valves is coordinated by an electronic engine controller. By isolating the fuel tank during the carbon canister purge, vapor spikes into the engine are eliminated, thus preventing engine stalls. Also, canister durability is improved by continuously storing and purging vapors in opposite directions.

A method is presented for diagnosing a condition in the fuel vapor purge system. The engine, the fuel tank and the carbon canister are connected in a three-way connection. The engine can be selectively isolated by a purge control valve, and the fuel tank can be selectively isolated by a fuel tank control valve. The operation of both valves is coordinated by an electronic engine controller. By isolating the fuel tank, and comparing the actual rate of change of the internal tank pressure (from the tank pressure sensor) to the estimated rate of change (from engine operating conditions) it is possible to determine if a condition occurred, and whether it is in the tank or in the vapor purge lines.

An ignition switch for turning a motor of the vehicle on and off also controls the application of electric power to the electric powered brake system. A control and method (FIGS.,and,) for maintaining application of full electric power to the electric powered brake system when the ignition switch is operated from ON to OFF so long as at least one parameter (,) related to a respective component of the vehicle and indicative of a need to maintain full electric power application to the brake system continues to exist and for discontinuing application of full electric power to the brake system when all of selected ones of several such parameters are indicative of lack of need to maintain full electric power application to the brake system.
