Automotive powertrain control systems

Control systems for the modern powertrain are defined by measures to reduce CO 2 and meet emission ceilings. Hybridization, downsizing and new combustion processes demand efficient algorithm structures with real-time capability. Exhaust-gas aftertreatment systems are using various catalyst concepts that require tailored sensor systems and regeneration strategies. And OBD functions are stretched to their technical limits in striking the balance between reliable fault detection and avoiding incorrect messages. All-electric drives are being developed alongside conventional hybridized and non-hybridized com-bustion engines. They provide greater degrees of freedom in designing the torque curve. Power-train control and battery management systems are opening up a whole new dimension in drivability characteristics. For the driver, top priority is given to reproducing them whatever the battery charge states
