Title: HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM (for LITHIUM-ION BATTERY with PA10): Drive Start Control; 2023 - 2025 MY Corolla HV [09/2022 - ] |
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
|
(a) Check if the customer operated the vehicle in a way that would cause the drive start control to operate.
Drive Start Control 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 (D or B) or R.
-
Pattern B (When all of the following conditions are met, control starts.)
-
Items Controlled
-
Hybrid system output is restricted.
-
Deactivation Conditions
-
The accelerator pedal is released.
-
The shift lever is in P or N.
-
The shift lever is in R.
-
The accelerator pedal is depressed excessively.
-
Items Controlled
-
Hybrid system output is restricted.
-
Deactivation Conditions
-
The accelerator pedal is released.
-
The shift lever is moved to any position other than R.
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.
