Braking confidence and pedal feel are important braking performance attributes that should be optimized to achieve customer satisfaction with a vehicle's braking system. The relationship between the input force and travel provided by the driver to achieve the desired vehicle deceleration is as core to the vehicle personality or DNA as ride, handling, or driveability.This Fast Track will cover the main concepts and methods needed for tuning brake systems to desired pedal force and travel characteristics.
In this one-hour, ten minute online short course, instructor Tom Hall will teach how braking confidence is defined in both objective and subjective terms, the relationships between input force and vehicle force will be developed. In addition, the relationships between input travel and vehicle deceleration will be developed. Effects of primary brake system subcomponents will be evaluated. Effects on component variability including frictional properties of brake pads will be studied
Is this Fast Track for You?
The Vehicle Braking Performance: Braking Confidence and Pedal Feel Fast Track would be of value to anyone involved in the validation of a braking system, either in the development of the validation plan or the execution of the validation plan. This course would also be of value to those involved in vehicle marketing -- a detailed understanding of the metric's generation and contributing effects will insure that promotion and comparison is done in a qualified manner.
By participating in this Fast Track short course, you will be able to:
- Explain the general mechanism by which pedal force is converted to stopping force and vehicle deceleration by the brake system
- Determine the amount of stopping force and deceleration that will occur for a given pedal force and pedal travel
- Explain the general parametric relationships between pedal force, travel and vehicle deceleration, and how to adjust key parameters to achieve pedal force, pedal travel and vehicle deceleration targets
- Explain how external factors such as elevation and temperature affect braking performance
- Identify the challenges related to braking design and braking confidence optimization for emerging technologies such as regenerative braking capabilities of hybrid and electric vehicles
- Introduction to Braking Confidence
- Input Force to Vehicle Deceleration Relationship
- Input Travel to Vehicle Deceleration Relationship
- Parametric Analysis
- Environmental Effects
- Emerging Trends Affecting Braking Confidence
