Abstract
An enhanced emergency brake assist system includes an accelerator pedal operated by the driver coupled to a braking system and used to control the overall vehicle speed. When a forward detection apparatus detects an imminent contact, the braking system automatically applies braking force to the vehicle after the driver fully releases the accelerator pedal. The braking force may be reduced when the driver or passenger are unbuckled.
Claims13
An enchanced emergency brake assist apparatus comprising:
- an accelerator pedal coupled to an accelerator position sensor, said accelerator position sensor being operative to generate an accelerator position signal;
- a braking system coupled to a variable brake booster, said variable brake booster being operative to produce a variable brake booster force;
- a driver seatbelt switch operative to generate a driver unbuckled signal when a drive seatbelt is unbuckled;
- a forward detection apparatus having control logic operative to detect an imminent contact and generate an imminent contact signal;
- and
- a controller coupled to said variable brake booster and said driver seatbelt switch, said controller being operative to receive said accelerator position signal, said driver unbuckled signal, and said imminent contact signal, said controller including control logic operative to automatically apply said variable brake booster force in response to said accelerator position signal and said imminent contact signal when said accelerator pedal transitions from a depressed position to a fully released position and reduce said automatic braking force when said driver seatbelt is unbuckled.
An enhanced emergency brake assist system for a vehicle comprising:
- an accelerator pedal located in the vehicle and coupled to an accelerator position sensor, said accelerator position sensor being operative to generate an accelerator position signal;
- a braking system located in the vehicle and coupled to a variable brake booster, said variable brake booster being operative to produce a variable brake booster force;
- a driver seatbelt switch operative to generate a driver unbuckled signal when a driver seatbelt is unbuckled;
- a forward detection apparatus located in the vehicle and having control logic operative to detect an imminent contact and generate an imminent contact signal, said forward detection apparatus operative to notify a driver of said imminent contact;
- and
- a controller located in the vehicle, coupled to said variable brake booster and said driver seatbelt switch, said controller being operative to receive said accelerator position signal, said driver unbuckled signal, and said imminent contact signal, said controller including control logic operative to automatically apply said variable brake booster force in response to said accelerator position signal and said imminent contact signal when said accelerator pedal transitions from a depressed position to a fully released position and reduce said automatic braking force when said driver seatbelt is unbuckled.
