Abstract
A diagnostic method for an a posteriori analysis of behavior of a vehicle braking system, the braking system including a regenerative braking mechanism, an additional braking mechanism, and a distribution device, the method including storing, in a non-volatile memory, at least one current value of a braking parameter from the distribution device for subsequent analysis based on the at least one value stored in the non-volatile memory, wherein the storage is triggered by execution of at least one event.

A diagnostic method for an a posteriori analysis of behavior of a vehicle braking system, the braking system including a regenerative braking means, a complementary braking means, and a distribution device configured to generate, from a global braking setpoint, a regenerative braking setpoint configured for the regenerative braking means, and a complementary braking setpoint configured for the complementary braking means, the method comprising:
- a storage for storing, in a non-volatile memory, at least one current braking parameter value obtained from the distribution device for a subsequent analysis based on the at least one value stored in the non-volatile memory,
- wherein the storage is conditional on execution of at least one event.
