Masina este de marca. Problema este ca producatorul nu este cunoscut in sectorul consumer.
-ATD ? Active Torque Dynamics. P2 has been fitted with Prodrive?s ATD system. During the last five years, Prodrive has been developing this system and has already built 12 demonstrators for a variety of vehicle manufacturers for different applications on four, rear and front wheel drive cars, ranging from large SUVs to supercars. The principle of ATD is to keep a vehicle going where the driver wants it to go, by modulating the torque at the road wheels using active differentials rather than applying the brakes, as is the case with stability systems such as ESP. "Road cars are generally driven in the ?linear region? where a certain input to the steering wheel results in a corresponding cornering rate of the car," said Damian Harty, chief engineer, dynamics. "However, when something unexpected happens, drivers tend to apply more steering angle than the vehicle can actually follow (around 10 degrees at the roadwheels). The vehicle behaviour changes significantly and the car does not go where the driver wants. This change is enough to confuse many people at a critical moment and often leads to loss of control in emergency situations. ATD extends this ?linear? region, making the vehicle much more controllable in emergencies." ATD uses data from wheel speed sensors (which can be shared with the antilock braking system), a yaw rate sensor and a steering wheel angle sensor to compare what the driver is requesting with what the vehicle is providing. If the driver is accelerating, or has some throttle applied, a torque can be applied to the appropriate wheel to counter oversteer or understeer. If they are braking, or off throttle, the system can be integrated with a conventional stability programme and brake the opposite wheel to enhance directional stability while reducing vehicle speed. On P2, which is all wheel drive, the ATD system uses an active centre and active rear differential to modulate torque between the front and rear axles as well across the rear axle. Where appropriate, this allows the vehicle to enter a corner with the favourable dynamics of a rear-wheel drive car to minimise power understeer, then progressively increase torque to the front wheels as it moves around the corner. As the vehicle leaves the corner, the torque split can be biased towards the front wheels to provide maximum straightening force to help correct any oversteer or, alternatively, to help induce a powered drift. With the active rear differential, P2 can also be given additional high speed stability for example in the event of an emergency lane change manoeuvre. By electronically controlling the lock on the rear differential, the car is provided with the agility to steer around an obstacle but then given added stability to help stop it spinning while returning to its path. Harty says that the system has significant benefits compared with conventional brake-based stability programmes: "ATD is extremely responsive. It can predict the vehicle?s reaction to changes before it calculates the correction required, so can achieve the required wheel speed in around 70ms. Because it applies positive torque, working with the movement of the car, it also feels more natural, particularly to performance-orientated drivers. A brake-based stability system can not distinguish when a driver is deliberately pushing a car to its limits and when a driver really is in trouble. As a result, it has to always assume the driver is in trouble and so intervenes when driving hard so ruining the driving experience." In addition to P2, Prodrive has two dedicated ATD demonstrators: an all wheel drive system, similar to the P2?s, on a Subaru Impreza and a front wheel drive system fitted to a Ford Focus RS which helps correct torque steer. Both are available for test drives. |
