Ride And Handling Optimization - Project 8: Overview

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Changing between the driving modes alters various vehicle settings. For example, the engine's speed may alter, while at a constant accelerator pedal position. The Adaptive Damping (AD) system and the steering system may also feel heavier or lighter. These changes are not dramatic but are noticeable.

JaguarDrive Control (JDC) is a selectable vehicle optimization system. It is designed to fine-tune the driving characteristics of the vehicle to suit different driving conditions and styles. The JDC system allows the performance envelope of the vehicle to be stretched and prevents the necessity for a single, compromised configuration for all conditions.

The JDC uses a combination of various vehicle sub-systems to achieve the required vehicle characteristics for the mode selected. The following sub-systems with the help of their modules make up the JDC:

The Powertrain Control Module (PCM)
The Transmission Control Module (TCM)
The Anti-lock Brake System (ABS) control module with Dynamic Stability Control (DSC)
The Chassis Control Module (CHCM) with Adaptive Damping (AD) system
The steering system.

There are 2 systems which alter the vehicles driving characteristics. These are the JDC and DSC. JDC modifies whole vehicle characteristics across multiple sub systems while DSC controls vehicle stability and traction only. For additional information, Refer to: ANTI-LOCK CONTROL - STABILITY ASSIST - PROJECT 8

The JaguarDrive Switchpack (JDS) is located in the floor console. Pressing either of the 2 outer (selector) switches moves through and selects the different driving modes.

The currently selected driving mode's Light Emitting Diode (LED) warning indicator illuminates to confirm the selection. The message center displays the relevant driving mode icon and a temporary confirmation message. The selection of normal mode does not display a driving mode icon or create a confirmation message.

There are 2 other systems that assist the driver in controlling the vehicle in slippery and unstable driving conditions are also discussed in this information :

Low Traction Launch

Low traction launch helps to further enhance low speed maneuvering and pulling away from a standstill, in adverse conditions.

All Surface Progress Control

The all surface progress control helps the driver to maneuver the vehicle on slippery and unstable driving surfaces. Such driving surfaces can be for example, ice, snow, grass, gravel, sand, and mud. This also helps when pulling away from a standstill, ascending or descending an incline. The all surface progress control operates in either a forward or a reverse direction at low vehicle speeds.
