Emergency brake assistance system for assisting a driver of a vehicle when setting the vehicle in motion

In a vehicle having an accelerator pedal by which a driver of said vehicle asserts an intention to accelerate said vehicle, an accelerator pedal sensor connected to said accelerator pedal and configured to output an accelerator pedal signal, an environment sensor arranged and configured to sense a potential obstacle in front of said vehicle and to output an environment sensor signal, an engine for driving said vehicle, a brake for braking said vehicle, a speed sensor to sense a current speed of said vehicle, and at least one safety device including at least one of an electronic brake system configured to actuate said brake, an engine control device configured to control said engine, a visual warning device configured to emit a visual warning to said driver, an acoustic warning device configured to emit an acoustic warning to said driver, and a haptic warning device configured to emit a haptic warning to said driver,

• an improvement comprising an emergency brake assistance system which comprises:
• a collision risk detection unit connected to said environment sensor to receive said environment sensor signal, and connected to said accelerator pedal sensor to receive said accelerator pedal signal, and configured to determine a collision risk of a potential collision with said potential obstacle based on at least said environment sensor signal and said accelerator pedal signal;
• and
• a collision avoidance unit connected to an output of said collision risk detection unit, and configured to produce, at least one output connected to said at least one safety device, at least one collision avoidance signal based on said collision risk, so as to actuate said at least one safety device to prevent or reduce a severity of said potential collision with said potential obstacle;
• wherein said emergency brake assistance system is configured to implement an override condition based on certain values of said accelerator pedal signal indicating an intention of said driver to override said collision avoidance signal, so as not to actuate or to stop actuating said at least one safety device, and
• wherein said emergency brake assistance system is further configured to temporarily deactivate, for a specified time duration, said override condition when at least the following deactivation conditions pertain:
• a) said accelerator pedal signal indicates an intention of said driver to accelerate said vehicle, and
• b) said current speed of said vehicle is below a specified speed threshold.
