Problems solved by technology

[0005] Due to the structure, distribution and number of controllers within the various vehicle control subsystems in a vehicle, the management of increased complexity and the need for software updates has become a key challenge for manufacturers
This is especially a challenge for original equipment manufacturers (OEMs)
Additionally, embedded software executed by conventional ECUs continues to increase in line count, complexity and sophistication

Embodiment Construction

[0017] The present disclosure is directed to providing a centralized controller for streamlining the control of multiple electronic control units (ECUs) and their associated actuator modules within a vehicle. As mentioned above, conventional systems have intelligent, expensive, complex controllers embedded within each actuator motor. The ECU of the present application eliminates the redundant need for multiple smart controllers by providing a centralized or shared smart controller with reduced logic motors. This strategy is particularly advantageous for actuators that are in close proximity to each other.

[0018] The benefits and advantages of embodiments of the invention are various. By centralizing the control of two different ECUs (e.g., electrically adjustable steering wheel and electrically adjustable seats), it is possible to reduce the number of nodes within the ECU while using lower levels and lower costs at the actuators The motor control still provides the same fu...

Abstract

The present disclosure generally relates to providing a centralized controller for actuators within electronic control systems of a vehicle. An electronic control system within a vehicle computer system, having a first actuator for performing a first vehicle function, a second actuator for a performing second vehicle function and a controller coupled to the first actuator and the second actuator for controlling the first and second actuators is provided such that the controller is not embedded in either the first or second actuator. Embodiments of a centralized controller and a non-transitorymachine-readable medium on which a program is stored for providing instructions to a controller that utilizes the 1-Wire communication and / or PoE protocols are also provided. Advantages include centralized manufacturing, simplified diagnostics, and streamlined software upgrades, all of which result in reduced costs.

Description

technical field [0001] The present disclosure generally relates to electronic control systems within vehicles. More specifically, the present disclosure relates to providing a method for enabling control of a plurality of electronic control units (ECUs) and their associated actuator modules within a vehicle, such as an electrically adjustable steering column (steering wheel) and adjustable seats. Streamlined centralized controller. Background technique [0002] An electronic control unit (ECU) is any embedded system in automotive electronics that controls one or more of the electrical systems or subsystems within the vehicle. Some common types of ECUs include Engine Control Module (ECM), Powertrain Control Module (PCM), Transmission Control Module (TCM), Brake Control Module (BCM or EBCM), Central Control Module (CCM), Central Timing Module (CTM ), Generic Electronics Module (GEM), Body Control Module (BCM) and Suspension Control Module (SCM). Together, these systems are ...
