HYBRID / BATTERY CONTROL HYBRID CONTROL SYSTEM Drive Start Control

DESCRIPTION

The drive start control is controlled by the hybrid vehicle control ECU.

If the hybrid vehicle control ECU determines that the shift lever and accelerator pedal are operated abnormally, hybrid system output is restricted and, when necessary, a warning is displayed on the combination meter assembly.

CAUTION / NOTICE / HINT

HINT:: Even if the accelerator pedal position is maintained, the hybrid system output may increase when driving uphill and decrease when driving downhill. This is due to drive start control controlling the hybrid system output, and is not a malfunction.

PROCEDURE

1.PAST ACTIVATION CONFIRMATION

Check if the customer operated the vehicle in a way that would cause the drive start control to operate.

Activation conditions

Pattern A (When all of the following conditions are met, control starts.)

The accelerator pedal is open by approximately 1/5 or more.

The shift lever is moved from P to any forward position D (Including other forward shift positions) or R.

Pattern B (When all of the following conditions are met, control starts.)

The accelerator pedal is open by approximately 1/5 or more.

The shift lever is moved from R to any forward position D (Including other forward shift positions), any forward position D (Including other forward shift positions) to R, or N to R.

HINT:: Depending on the situation, the shift position may not be changed.

Items Controlled

Hybrid system output is restricted.

Deactivation Conditions

The accelerator pedal is released.

The shift lever is in P or N.

HINT:: ·

The hybrid system output restricted level differs between Pattern A, Pattern B and Reverse control.

·

During Shift control or Reverse control, hybrid system output is adjusted based on the road gradient.

·

Drive start control is not activated when TRC is turned off.

Control will also not operate under the following conditions. (if equipped)

*

When TRAIL mode is on

*

When multi-terrain select is selected
