BAS assists driver's by automatically increasing their braking power during an emergency brake event when the driver is unable to apply a sufficient brake force.. There are two performance requirements that BAS must fulfill in order to be employed effectively. One is the ability to activate when the driver suddenly applies brakes in an emergency while the other is the ability to provide additional assistance. Further study of BAS activation timing and degree of assistance in relation to driver acceptance is needed. The driver's acceptance of BAS refers to the BAS activation only during an emergency. A study was conducted to clarify drivers' emergency braking characteristics and measure the frequency of BAS activation during normal braking.
One aim of the study was to verify driver characteristics during emergency braking on a test course. The study measured the brake pedal speed, force, and stroke during emergency braking along with the driver's compatibility with BAS activation conditions. Another task was to evaluate BAS with a driving simulator (DS). This study measured the frequency of BAS activation during normal braking by varying the BAS activation timing and degree of assistance. It also examined what the effects and side effects of varying these BAS parameters on the driver.
In conclusion this study evaluates how varying BAS activation timing and its degree of assistance has on the drivers.
