| The MathWorks Tools Help Toyota Design for the Future |
|
Toyota adopted MathWorks tools like MATLAB, Simulink, Stateflow, and Real-Time Workshop as a total design solution. Toyota's initiative—and their development partnership with The MathWorks—was set in motion ten years ago, when the auto maker first chose MATLAB, then Simulink. "Our use of [these tools] has been gradually increasing," says Toyota spokesperson Akira Ohata; "We now have more than 400 licenses for MATLAB, Simulink, and Stateflow, and they have become the de facto standard at Toyota for simulation, data processing, and controls design. It would be impossible to list all of the applications for these tools at Toyota."

| Jaguar Reduces Development Costs with MathWorks Rapid Prototyping and Code Generation Tools |
|
To meet demands for increasingly complex new vehicles while continuing to reduce costs, where possible Jaguar develops and tests new functionality using existing production vehicles instead of building expensive prototypes. This approach involves adding a special-purpose electronic control unit (ECU) to the vehicle.

| MathWorks Products Save Money and Accelerate Fuel-Injection Technology Development at Ricardo |
|
Ricardo Consulting Engineers, which began over 80 years ago as a developer of internal combustion engines, has expanded into fuel cells, powertrain engineering, vehicle engineering, and fuel and lubricant development. A few years ago the company, which is based at Shoreham-on-Sea in England, began investigating gasoline direct injection (G-DI) engines.

| Simulink Aids Chassis Control Design at Delphi |
|
Delphi Chassis Systems needed to develop and test a new vehicle stability enhancement system that would control a skidding car via selective brake and engine intervention. At the same time, they needed to reduce design time and boost engineering productivity. Delphi used MATLAB, Simulink, and Real-Time Workshop, along with dSPACE bypass systems, to develop and test new control algorithms.

| Eaton Corporation Speeds Development of a Medium-Duty Hybrid Truck with xPC Target |
|
Eaton had been using Simulink, Stateflow, and the Control System Toolbox for designing and simulating powertrain configurations and their control algorithms. Faced with a short timetable, a limited budget, and very diverse I/O requirements on the hybrid electric powertrain project, they chose to use these same tools and to use xPC Target to implement the controller. This provided them with the flexibility they needed to run iterative tests in a cost-effective way. Dynamometer Testing.

| Automotive Systems Laboratory Tests Crash Sensors Using MATLAB and the Data Acquisition Toolbox |
|
Automotive Systems Laboratory-Takata is helping leading automotive manufacturers eliminate inadvertent airbag deployment by replacing the accelerometer with a magnetic sensor, which responds to disturbances much faster than the speed of sound in metal and detects disturbances at multiple points.

| UC Davis Students Develop an Environmentally Friendly Sport Utility Vehicle Using Simulink |
|
The UC Davis team developed a comprehensive vehicle model based on PSAT (Partnership for a New Generation of Vehicles Systems Analysis Toolkit), a Simulink based modeling program developed by Argonne National Laboratory. They simulated their Suburban’s four-wheel-drive powertrain to determine a control strategy, settling on a combination of charge-depletion and charge-sustaining strategies. In charge-sustaining vehicles, the onboard battery is recharged by the combustion engine while the vehicle is being driven. During charge-depletion, electric energy from the battery powers the vehicle. The vehicle is recharged when the driver returns home that night.

| Motorola Creates Electric Vehicle Battery Management Controller with Real-Time Workshop Embedded Coder |
|
Motorola Automotive had just completed a production-intent ECU for a global body seat controller on a model year 2002 vehicle using MathWorks model-based design and code generation products. “We knew that model-based design is well suited for managing changes in requirements and fast turnaround times, so we decided to use that approach here,” says Zeidan. “We selected the complete set of MathWorks products to avoid piecing tools together and working from a disjointed process.”

| Newman-Haas Automates Spring-Testing Using MATLAB and the Data Acquisition Toolbox |
|
In previous data-acquisition projects, NHR developed test setups using Visual C++ and other high-level language development environments. For the new project, they selected MATLAB and the MATLAB Data Acquisition Toolbox. The Data Acquisition Toolbox provided them with a seamless interface to a number of third-party data acquisition (DAQ) cards and allowed live data to be streamed into MATLAB for runtime analysis and visualization. Having all data collection and processing within the MATLAB environment enabled them to do more post-processing and to customize the graphic representation of results.

| Instron Develops a Multiaxis Test Fixture Using SimMechanics |
|
To improve efficiency, Instron used one integrated environment to model every component. They chose MATLAB, Simulink, and SimMechanics to simulate the controller and the test fixture concurrently. They could then use simulation results from the controller and the test fixture to improve the design of each.

Formed in 1983 as a partnership between actor Paul Newman and racing businessman Carl Haas, Newman-Haas Racing (NHR) engineers, partially manufactures, and fields cars in the Championship Auto Racing Teams (CART) series. CART is "the fastest and most competitive open-wheel racing series in the world" according to Racer magazine.
