Abstract

In a vehicle skid recovery system skid recovery can be accelerated when an automotive vehicle begins to skid as a result of ice accumulation on the road surface. The system can control operation of ice removers (e.g., blades or heaters), which are mounted within the wheel wells forward of the wheel, based on information received from the vehicle'"'"'s outside temperature sensor and anti-lock braking system (ABS). When the temperature sensor indicates that the outside temperature is below a predetermined temperature and when the anti-lock braking system is activated as a result of detected skid, a controller activates the ice remover in one or more of the wheel wells and, thereby cause the ice remover to remove ice from the road surface forward of the corresponding wheel. Clearing the ice allows the vehicle'"'"'s tires to gain traction on the road surface and, thereby stops the skid.

Claims

1. A vehicle skid recovery system comprising:

a temperature sensor sensing a temperature outside a vehicle;

an anti-lock braking system operably connected to brakes on said vehicle;

a blade movably mounted within a wheel well of said vehicle forward of a wheel, said blade having a scraping edge;

a piston operably connected to said blade;

a brake fluid line extension containing brake fluid and connected by a valve to a brake fluid line of said vehicle;

a controller in communication with said temperature sensor and said anti-lock braking system,

said controller being operably connected to said valve and to said blade,

said controller causing said blade to move from a first position within said wheel well to a second position, when said anti-lock braking system is activated and said temperature is below a threshold temperature, said second position allowing said scraping edge to displace ice that is on a surface forward of said wheel, and

said controller causing said blade to move from said first position to said second position by opening said valve to increase brake fluid pressure within said brake fluid line extension and said piston such that said piston moves said blade from said first position to said second position; and

,

a pressure sensor mounted on said blade, said pressure sensor measuring an amount of pressure being exerted against said blade by any one of said ice and other material and said controller being in communication with said pressure sensor and causing said blade to move to a third position based on said amount of said pressure.

2. The vehicle skid recovery system of claim 1, said brake fluid pressure rising and falling as a function of said anti-lock braking system such that said blade is intermittently moved away from said surface.

3. The vehicle skid recovery system of claim 1, said blade being angled such that said ice displaced by said scraping edge is moved away from said vehicle.

4. The vehicle skid recovery system of claim 1, said blade being essentially chevron-shaped such that a first portion of said ice displaced by said scraping edge is moved beneath said vehicle and a second portion of said ice displaced by said scraping edge is moved away from said vehicle.

5. The vehicle skid recovery system of claim 1, said blade being arched such that a first portion of said ice displaced by said scraping edge is moved beneath said vehicle and a second portion of said ice displaced by said scraping edge is moved away from said vehicle.

6. The vehicle skid recovery system of claim 1, said blade being movably mounted within a protective compartment within said wheel well, said compartment having openings allowing said blade to move from said first position to said second position and allowing for blade replacement.

7. The vehicle skid recovery system of claim 1, further comprising an activation switch on a cockpit of said vehicle, said controller being in communication with said activation switch and activating said vehicle skid recovery system only be when said activation switch is “

on”
