Installation of anti-lock brake systems (ABS) and electronic stability control (ESC) has grown steadily over the past few decades, and is expected to grow significantly. Total demand for ABS and ESC systems increasing with four wheel speed sensors per system. ABS has become standard in new vehicles. NXP Semiconductors has shipped more than half a billion ABS speed sensor modules, with Continental automotive supplier.

NXP and Continental are the leading suppliers of speed sensors using Magnetoresistive (MR) technology. Working together in close cooperation, the two companies have been leading the introduction of automotive products with Magnetoresistive technology in the marketplace. The Chassis & Safety Division of Continental has worked closely with NXP to develop advanced ABS/ESC sensor modules that are now used by most car manufacturers in the world, in both the standard and high-end segments of the market.

“The reliability, precision and functionality of our wheel speed sensors are key for our leading position in the global market– and our close collaboration with NXP has been important to our success,” said Dr. Bernhard Klumpp, executive vice president, Business Unit Sensorics, Continental. “Our wheel speed sensors also form a foundation for our advanced driver assistance – systems such as Emergency Brake Assist City, which can prevent nose-to-tail collisions in urban traffic.”

NXP’s high-quality rotational Magnetoresistive (MR) sensors can accurately and reliably detect and measure wheel speed. MR sensors offer clear advantages over devices employing other sensing methods: they are very precise and very robust in harsh automotive environments, since they operate with low noise and suffer less from drifts due to age or thermal influences. Due to their high accuracy, NXP’s ABS/ESC sensor modules can even be used for certain tire-pressure monitoring functionality. The NXP portfolio also includes high-end sensors, including the first sensor on the market with the new VDA protocol amongst many others. The high-end sensors provide increased performance, advanced fail-safe features and improved signal processing, which enable safety and driver-assistance functions such as ESC, hill-holder systems and parking assistance.
