Recently, the existence of vehicle controls function which is helpful for the vehicle safety and convenience requirment while driving is becoming the main factor for the customer’s vehicle choice and many customers are trying to understand the safety function. As the total performance of the vehicle is increased, making high performance of the vehicle dynamics is also important as well as making high performance of the engine to satisfy the customer’s demand. The essential precondition for matching with this customer’s demand is directly connected to reliable brake performance with high performance of chassis systems. For this reason, many automobile manufacturer are trying to compensate the hardware-wise limitation and secure the strong performance of brake systems by using value added functions of ESC.
Brake Prefill function is one of value added functions of ESC, it detects driver’s brake pedal input in advance and adds the decided brake pressure at each brake corner module prior to the driver’s actual brake input so the function can compensate of brake response time at emergency braking situation. Reduction of brake response time means the function can decrease vehicle collision probability by driver’s brake input delay at emergency braking situation so the function is very meaningful for enhancement of vehicle stability performance and it becomes more effective at high speed braking in particular. But if the function adds excessive brake pressure to bring brake response time into focus, then customers can complain the different brake pedal feeling while Brake Prefill function activates. For this reason, the balance between brake response time and brake pedal feeling is essential factor for the function implementation of Brake Prefill.
In this paper, we conducted the customer clinic to find out Korean customers’ demand about Brake Prefill function and the analysed the result by Loss Function. Based on the analysed result, we suggest the analysis method for Brake Prefill function to satisfy Korean customers’ demand using the customer clinic with Loss Function.
