Control mechanism and display for hybrid vehicle
First Claim
1. A control mechanism for a hybrid vehicle comprising a motor driving means enabling a running of the vehicle through an output of an electric motor, an engine driving means enabling the running of the vehicle through an output of an engine, a throttle sensor for sensing an opening degree of a throttle valve of the engine, and a driving change-over control means having a mode map for determining each of working regions (M, E) of the motor driving means and the engine driving means in response to a sensing signal (θ
- ) of the throttle sensor,wherein said mode map is provided with a critical region (Ma) adjacent to the working region (E) of the engine driving means in the working region (M) of the motor driving means and an informing means for informing a driver of a fact that the motor driving means is being operated in the critical region (Ma),wherein the critical region (Ma) of the mode map is limited to a predetermined maximum value (a) of the sensing signal (θ
) of the throttle sensor, and by a predetermined maximum value (b) of an opening speed (dθ
/dt) of the throttle valve.

Abstract
A control mechanism for a hybrid vehicle having a motor driving means enabling its running through an output of an electric motor, and an engine driving means enabling its running through an output of an engine, includes a throttle sensor and a driving change-over control unit having a mode map for determining each of working regions M, E of the motor driving unit and the engine driving unit in response to a sensing signal θ of the throttle sensor. The mode map is provided with a critical region Ma adjacent to the working region E of the engine driving unit in the working region M of the motor driving unit and an informing unit (display device) to inform a driver of a fact that the motor driving unit is being operated in the critical region Ma. The display device also indicates a battery residual amount.
