ESC efficiency to reduce accident is now well proven. To obtain this accident reduction tests employed for the tuning of a car equipped with an ESC must be related to real world accident cases. With accident statistics obtained in France, two main categories of accidents are defined:​ loss of control in a curve and accidents in a straight line or at an intersection. For each of these categories, thanks to detailed analyses of real accidents, we can define tests scenarios that are related to real world. Several examples are given.

To measure the performance of a car equipped with an ESC during these tests, stability criteria are defined. In addition criteria to assess the quality of ESC intervention are defined. These tests pointed some limitations of ESCs. Some improvements of ESCs algorithms were specified to overcome these problems. Examples are given.

During this ESC tuning, it is decided if a rollover prevention module is necessary or not. This decision process, which includes both real tests and HIL (Hardware In the Loop) tests is described. One of the conditions that may lead to a rollover is a contact between the rim and the ground. This process also enables us to define test conditions to check there is no risk of rim contact on the ground.

A test method of a tyre on a bench to check these conditions are satisfied is described. It is also shown that the risk to have a contact of the rim on the ground is not significantly modified during the brake activation by the ESC.
