It addition, ON/OFF switch 10 can be installed on handle or the driver such as instrumental panel, console other positions maneuverable of not gear lever 15.
The position of gear lever sensor 20 perception gear lever 15 in the sport mode, passes to driving control portion 50.
In the sport mode, the position of gear lever 15 is as in figure 2 it is shown, can be divided into the neutral position of the situation 21 that non-driver inputs and input 22 according to the upshift of driver and the upshift position of movement ('+' position) and the downshift position of movement ('-' position) according to the downshift input 23 of driver.
Now, after gear lever 15 is moved to upshift position or downshift position by driver, if driver puts down hands from gear lever 15, then return to neutral position by means of mechanical spring structure.
Therefore, input the input time of 22 and downshift input 23 according to the upshift of driver, determine gear lever 15 in upshift position or downshift position residence time.
Gear lever sensor 20 can gear lever 15 so according to upshift input 22 upshift position residence time and according to downshift input 23 in downshift position residence time, together pass to driving control portion 50 with the position of gear lever 15.
The brake pedal input of brake pedal sensor 30 perception driver, passes to driving control portion 50, the accelerator pedal input of accelerator pedal sensor 40 perception driver, passes to driving control portion 50.
If driving control portion 50 delivers, by ON/OFF switch 10, the ON signal making operational mode open, then according to the position of the gear lever 15 from gear lever sensor 20 transmission, control control portion 90 of EMS control portion 70 and EPB, make vehicle acceleration or deceleration.
First, if the position of gear lever 15 inputs 22 according to the upshift of driver and is in upshift position, driving control portion 50 then controls EMS control portion 70, makes vehicle accelerate.
Now, driving control portion 50 can calculate the accelerator pedal signal being directly proportional to gear lever 15 in upshift position residence time, passes it to EMS control portion 70.
