A method for providing an estimate of brake pad thickness. The method employs fusion of sensors, if used, and driver brake modeling to predict the vehicle brake pad life. An algorithm is employed that uses various inputs, such as brake pad friction material properties, brake pad cooling rate, brake temperature, vehicle mass, road grade, weight distribution, brake pressure, brake energy, braking power, etc. to provide the estimation. The method calculates brake work using total work minus losses, such as aerodynamic drag resistance, engine braking and/or braking power as braking torque times velocity divided by rolling resistance to determine the brake rotor and lining temperature. The method then uses the brake temperature to determine the brake pad wear, where the wear is accumulated for each braking event. A brake pad sensor can be included to provide one or more indications of brake pad thickness from which the estimation can be revised.

Errors in current methods of determining elastic modulus through depth-sensing indentation may be resulted from three major factors: 1. error in estimating the projected contact area A(h_c) by indirect means such as from the unloading curve, especially in the cases where “piling-up” occurs; 2. reliance on the use of the initial unloading slope S_u, which in some cases is not easily determined reliably; and 3. insufficient consideration on the influences due to indenter bluntness in some important models based on numerical treatments. This invention provides a new method of determining elastic modulus of an indented material, which overcomes the above deficiencies. The maximum load and the total displacement of the indenter (to give a nominal hardness defined in this invention), elastic work and total work are measured. From these data, the reduced elastic modulus is thus determined through a set of function-like relationships established in this invention, which is then used to calculate the elastic modulus of the indented material.

One embodiment of the present invention sets forth a technique for more effectively utilizing graphics hardware by allowing the developer to exploit parallelism at the primitive-level. In this technique, an algorithm is analyzed to break the total work associated with processing one primitive into discrete portions of work. The results of this analysis are used to program a geometry shader group that includes multiple geometry shaders. Upon receiving a single input primitive, the geometry shader group launches multiple parallel threads, one thread in each geometry shader in the group corresponding to each discrete portion of work. As each thread completes, the output of the thread is stored in on-chip GPU memory for processing by the next stage in the graphics pipeline. Since the overall work associated with a given input primitive is distributed across multiple threads, the output of each thread is smaller and, thus, the total memory required to implement the algorithm is reduced.
