Long KpV(100)x0.01

LongTuningKpV

Longitudinal proportional gain for immediate error response. Hyundai, Kia, and Genesis are fixed at Kp 1.0 for safety, so this setting is hidden and ignored on those vehicles. Toyota/Lexus fix the common Kp=0 to avoid duplicate correction before their dedicated controller; this setting is hidden and saved values are ignored.

• Type: Number
• Default: 100
• Range: 0 ~ 200
• Step: 5
• Menu: Driving > Cruise & Gap > Accel/Brake Tuning

Behavior

Sets the longitudinal proportional term that responds immediately to speed error.

• Higher: Increases the contribution of this longitudinal-control term.
• Lower: Reduces that contribution.

Volkswagen MEB vehicles, including ID.4, have single-point Kp and Ki tunes, so saved Kp/Ki/Kf settings apply. Updating does not reset previously saved values. Hyundai/Kia/Genesis fix common Kp/Ki/Kf at 1/0/1. Toyota/Lexus fix them at 0/0/1 because their dedicated vehicle controller already corrects acceleration tracking. Both brand families hide and ignore these three saved settings; stopping control and acceleration limits remain active.

Usage

Use small, one-at-a-time changes for the same target-speed transition and compare overshoot, oscillation, and response delay.

Reference

Caution

Incorrect values can reduce steering or longitudinal stability and comfort. Change one item in small steps and restore the default if behavior becomes abnormal.
