And the addition
of braking force control allows the system to realize vehicle behavior that more closely mirrors driver intent.
The loss of vacuum pressure will result in a
reduction of braking force and a hard brake pedal, increasing the risk of a motor vehicle crash.
It then calculates the
level of brake force needed to correct the car's direction and, via the ABS system, applies that precise braking force to individual inner wheels as necessary.
However, when a vehicle is turning or under full braking load, the
amount of brake force that can be used by one wheel may differ from that of another.
To help optimize braking performance for a variety of vehicle loads, EBD adjusts the amount
of brake force applied to the front and rear wheels for improved braking performance, reduced front - end «dive» during braking and more even brake wear.
It is very effective, however, and creates immense amounts
of braking force which significantly extends friction brake life — a 565 hp (421 kW) diesel engine can produce up to 600 hp (450 kW) of braking power at 2,100 RPM.
Of the approximately 10 cm worth of pedal travel the Haval H2 possesses, the first 5 cm offer nothing in the
way of brake force, whilst the next 3 cm suddenly deliver a good 70 % of the braking ability all at once.
This feature uses a slight — virtually imperceptible to the driver — amount
of braking force on the outside front wheel when accelerating through a corner.
When operating as a generator in Brake Energy Regeneration, the electric motor produces approximately 27
hp of brake force.
EBD varies the amount
of braking force applied to each of the wheels depending on the wheel speed, road conditions and load in the car.
Torque Vectoring Control, which automatically applies small
amounts of brake force to limit wheel spin at the front axle, further enhancing available tractive force.
Foot braking only will likely cause wheel lockup, as the ABS system has limited capabilities at low speeds and whithout it you are applying the same amount
of braking force to all wheels.
A rear wheel drive vehicle will realize theoretically, an advantage when braking on ICE over a front wheel drive vehicle because the proportioning valve sends as much as 67 % -70 %
of the braking force to the front wheels anyway.
While
some of the braking force is produced due to friction in the drive train, this is negligible compared to the effect from the manifold vacuum caused by the air - flow restriction.
If more than 40 %
of braking force is required, you'll receive an audible and visual warning to intervene by applying more braking force.
Torque Vectoring by Braking (TVbB), which intelligently and rapidly applies precise amounts
of braking force to individual wheels to accurately sharpen the car's line through a corner, is standard.
When the driver requires only a small amount
of brake force, the system uses only the drag of the electric generator (motor).
When the driver applies the brake pedal, a signal is sent to the vehicle's Electronic Control Unit (ECU), which determines the appropriate amount
of braking force to assign to regenerative braking through the electric drive motor and to the hydraulic friction braking system.
If you don't react, the car will deploy 40 %
of the brake force to limit impact.
