Abstract
A liquid sprayer control method to induce drift driving for a vehicle, wherein the control apparatus includes a liquid sprayer attached to a tank of fluid, which in turn has two small hoses aiming towards the rear tires of a vehicle. With a simple push-button controller at the driver’s command, the driver sprays liquid onto the rear tires, coating them for an effective loss of traction of the rear tires, allowing the driver to induce a drift, or intentional loss of rear traction of the vehicle for closed-course exhibition or educational purposes.
Claims
1. A method of controlling implementation of a drift driving state of a vehicle, the method comprising: inducing, by a spray controller, the rear wheels to lose traction when the driver decides to go into a drift, the vehicle’s rear tires are coated with lubricant solution in order for the vehicle to enter into a rotary driving, or drift; allowing, by the spray controller, the vehicle enters into drift driving state for as long as the driver can maintain it using the spray controller.
2. The method of claim 1, wherein the slip control torque determined to be decreased as the lateral acceleration of the vehicle increases.
3. The method of claim 1, wherein the slip of the rear tires is activated through the driver’s control, can and will be maintained as long as the sprayer continues to spray lubricant onto rear tires or until driver releases controller and torque, whereby, the vehicle will seize to remain in drift state.

DETAILED DESCRIPTION
[0006] The following description relates to systems and methods for operating a driveline or powertrain of a Front engine, Rear wheel drive (FR) vehicle. FIG. 1 shows an example of the typical layout of a FR vehicle that includes driveline, transmission, driveshaft and rear differential. When slipping, or the skidding of the rear wheels occurs via the output of the torque of the transmission through driver input, much effort has to be applied in order for a vehicle to go into a drift. A method of controlling implementation of a drift driving state of a vehicle according to an exemplary embodiment of the present invention is applied to the vehicle as above, so drifting of the vehicle is possible whenever the driver desires. The system, collectively, is designed to work best in a vehicle with a front-engine, rear-wheel drive (FR) setup though it can work in other applications such as on vehicles with front-engine, front-wheel drive (FF) or even on vehicles equipped with all-wheel drive (AWD) setups and the system can yield similar results. For the purposes of the diagrams and for simplicity’s sake, we’ll refer to this invention for what it was intended to work best on; the front-engine, rear-wheel drive (FR) setup as it is the most common platform for police and other emergency vehicles as well as racing vehicles for the sport of drifting or other closed-course exhibitions.
[0007] The system works in detail by (FIG. 3); [0008] 1. The installed button controller 1 connected to an electric wire 2 to a safety kill switch 3 located in the trunk or rear of the vehicle to prevent accidental use of the system, which in turn when activated, at will, turns on a small electric liquid sprayer 4 that is connected to a fluid liquid tank 5 with an inlet rubber hose 6 that is located in the trunk or rear of the vehicle which is also connected to two plastic hoses 8 that are installed on top of the two rear tires with sprayer nozzles 7 at the tips to evenly and efficiently coat the rear tires on demand. [0009] 2. When the driver desires to enter into a drift, the driver sprays the rear tires by holding down the button for as long as the driver desires, usually a few seconds, until the rear tires are ‘primed’ for the driver’s maneuvers. [0010] 3. The driver, once having coated the rear tires, will enter into a drift state by slip torque by accelerating and counter steering, in which the driver operates a steering wheel opposite direction to rotation, maintaining the drift via the momentum of the weight of the vehicle until the driver reduces the speed of the car via deceleration as shown in FIG. 2.
