A process for braking a vehicle having at least first and second brakes, comprises supplying energy to the first and second brakes so as to actuate them, the energy being distributed between the first and second brakes in accordance with the brakes' response energies. Preferably, the momentary values of the response energies are used so that the first and second brakes are actuated simultaneously. The momentary values of the response energies of the brakes may be determined as follows: (a) measuring the existing vehicle deceleration to determine a value of ground-vehicle deceleration, (b) supplying a braking test energy to the brake being tested, (c) measuring the deceleration of the vehicle after the braking test energy has been supplied to the brake being tested in order to determine a value of vehicle test deceleration, (d) comparing the value of ground-vehicle deceleration with the value of vehicle test deceleration, and (e) if the value of vehicle test deceleration is greater than the value of ground-vehicle deceleration by more than a predetermined tolerance value, repeating steps (a) to (d) with a reduced braking test energy until the difference between the value of vehicle test deceleration and the value of ground-vehicle deceleration is decreased to no more than the predetermined tolerance value, or (f) if the value of vehicle test deceleration is equal to or less than the value of ground-vehicle deceleration, repeating steps (a) to (d) with a higher braking test energy until the value of vehicle test deceleration exceeds the value of ground-vehicle deceleration by a value which is less than or equal to the predetermined tolerance value. The energy supplied to the brakes to actuate them may be in the form of pressure.
A process for braking a vehicle having at least first and second brakes, comprising:
A process for braking a vehicle having at least first and second brake actuable by supplying energy to said first and second brakes, each of said first and second brakes beginning production of a braking force only after the supplied energy is equal to or greater than a response energy which is specific for each of said first and second brakes, said process comprising starting a brake application in said vehicle by simultaneously supplying energy to each of said first and second brakes that is equal to its respective response energy, thereby causing said first and second brakes to begin production of a brake force simultaneously, wherein a momentary value of the response energy of at least one of said first and said second brakes is determined in at least one brake actuation and wherein the distribution of said energy between said first and second brakes is based on said momentary value, and wherein the momentary value of the response energy of said at least one brake is determined as follows:
