When a diagnosis result of an ABS control system is normal, a determination is made as to whether or not to execute ABS control based on a slip ratio of a vehicle wheel, whereupon motor torque control is executed based on an operational state of an ABS. In other words, when ABS control is not executed, the motor-generator is controlled to a regenerative state, and when ABS control is executed, the motor-generator is controlled to a power running state. When the diagnosis result of the ABS control system is abnormal, on the other hand, regenerative braking by the motor-generator is prohibited immediately and the motor-generator is controlled to the power running state.

Control apparatus for electric vehicle

The present invention provides a driving force control unit for a vehicle having an accelerator opening degree detecting unit for detecting accelerator opening degree, a driving condition detecting unit for detecting engine driving condition, a driving force setting unit for setting a driving force indication value according to a plurality of different driving force characteristics based on the accelerator opening degree and the engine driving condition, a selector for selecting a driving force characteristic from the plural of different driving force characteristics by manipulation. The driving force setting unit setting the driving force indication value according to the selected driving force characteristic.

Driving force control unit for vehicle

The present invention provides a vehicle display device which allows a driver to instantaneously grasp driving force information. A meter_ECU displays a driving force display image which displays driving force information of a vehicle on an MID, displays an acceleration-torque line (driving force characteristic line) L corresponding to the currently selected mode M and, at the same time, changes a power level which is indicated in a power display region P set within the acceleration-torque line L interlockingly with an accelerator operation of a driver. Due to such a constitution, the vehicle display device allows the driver to instantaneously grasp the driving force information.

Vehicle display device

The present invention provides a vehicle display device which can display fuel consumption information of a vehicle in a useful and optimum mode for a driver. A meter_EUC calculates an instantaneous fuel consumption of a vehicle based on a mileage and a fuel injection quantity within a set time, calculates an average fuel consumption of the vehicle based on respective cumulative values of the mileage and the fuel injection quantity repeatedly calculated for every set time, and displays the deviation of the instantaneous fuel consumption with respect to the average fuel consumption as fuel consumption information on a fuel consumption meter. The display on the fuel consumption meter is performed by swinging a pointer with respect to a neutral position. When the deviation takes a positive value, the pointer is swung in the pulse direction with a swinging width corresponding to the deviation quantity, while when the deviation takes a negative value, the pointer is swung in the minus direction with a swinging width corresponding to the deviation quantity.

The driving force control unit for a vehicle comprises a plurality of control modes for controlling a driving force, each of control modes having each driving force characteristic, a vehicle driving condition detecting unit for detecting a vehicle driving condition, a selector for selecting one control mode from the control modes, a temporary selector for changing the current mode to other mode, and a driving force indication value setting unit for setting a driving force indication value according to the vehicle driving condition and the driving force characteristic corresponding to the selected mode by the selector or the temporary selector.

Driving force control unit for a vehicle

The driving force control unit comprises a plurality of control modes for controlling a driving force, each of control modes having each driving force characteristic; a vehicle driving condition detecting unit for detecting a vehicle driving condition; a selector for selecting one control mode from the plurality of control modes; a driving force setting unit for setting a driving force indication value according to the driving force characteristic selected by the selector based on the vehicle driving condition; and a shift lever position detector for detecting a shift lever position of a transmission. The control mode includes a reverse control mode having a reverse driving force characteristic suitable for traveling the vehicle in reverse direction. The driving force setting unit changes the control mode to the reverse control mode when the shift lever is detected in a position of a reverse range, and sets the driving force indication value according to the reverse driving force characteristic.

A driving force control device can set driving force characteristics which conform to tastes of drivers using one vehicle thus giving the easy-to-drive feeling to the drivers. An E/GECU possesses three modestoas control modes and selects one mode from these modes based on a manipulation input using a mode selection switch. Further, any one of the mode out of these modestois preset in the E/GECU as a temporary changeover mode, and the E/GECU changes over a mode selected by the mode selection switch and the preset temporary changeover mode alternatively by the temporary changeover switch.

Driving force control device of vehicle

The driving force control unit for vehicle comprises a driving condition detecting unit for detecting the vehicle driving condition, a selector for selecting one of driving modes by manipulation, the driving modes including a first mode having a driving force characteristic suitable for normal driving and a second mode having a suppressed driving force, and driving force setting unit for setting a driving force indication value based on the selected mode and the vehicle driving conditions. The selector being formed by a multiple switch having a push switch which turns to ON state when a pressing force direction manipulation is applied, and other switch which turns to ON state when manipulation other than the pressing force direction is applied, the second mode is selected by the ON manipulation of the push switch.
