Tesla’s newest patent particulars a brand new steer-by-wire system, with a supposed devoted group able to combine this know-how into its electrical car lineup.
The steer-by-wire system goals to rework the normal steering mechanism by eliminating mechanical linkages, as a substitute counting on electrical or electromechanical methods, stories Electrek. This know-how has the potential to reinforce effectivity, supply superior steering configurations, and pave the way in which for revolutionary car cockpit designs.
At present, many areas require mechanical linkages in steering methods for a car to be deemed road-legal. Tesla, together with quite a few automakers, has already included motors and actuators for drive controls to help options like Autopilot and Full Self-Driving. Nonetheless, these methods are nonetheless mechanically linked to the steering system.
In 2020, Electrek reported that Tesla was assembling a brand new group in Austin to develop this steer-by-wire system. Subsequently, in 2021, Tesla’s CEO Elon Musk confirmed the corporate’s concentrate on the event of a progressive steer-by-wire system, noting it might nonetheless be years till fruition.
The patent not too long ago filed by Tesla offers a glimpse into the corporate’s imaginative and prescient for this know-how. The applying’s summary outlines a car steering system by wire designed to manage the car’s lateral movement. This method incorporates a steering wheel torque suggestions actuator meeting with two controllers, a entrance street wheel steering actuator meeting with two remoted motors and controllers, two separate energy assemblies, two separate car communication networks, and three non-public system communication networks for every node within the steering system.
This configuration ensures the system’s resilience by isolating faults, stopping a single part failure from endangering your complete system. Furthermore, the system might embrace a differential gearbox street wheel actuator to facilitate absolutely the positioning of the street wheels, additional enhanced by a set of place sensor assemblies.
Tesla’s design showcases a novel strategy that gives redundancy with out counting on a backup mechanical steering system. This improvement marks a major stride in Tesla’s quest to redefine the automotive business and create a extra environment friendly, sustainable future.
