Advanced vehicle safety systems realise the best potential in reducing traffic accidents and fatalities, to be effective they must operating on large numbers of vehicles. In 2015 Toyota launched the democratisation of the technologies in its cars with Toyota Safety Sense, which includes active safety features designed to help provide prevention or mitigation for the consequences of collisions across a broad range of traffic situations.
Toyota is aiming to make Toyota Safety Sense a standard feature or an option affordable to a large numbers of its clients, Toyota is striving to help large numbers of motorists – and indeed other road users – through the benefits of the safeguards this system can provide.
The package includes a Pre-Collision System (PCS), Lane Departure Alert (LDA), Road Sign Assist (RSA) and Automatic High Beam (AHB). Vehicles equipped with a millimetre-wave radar further benefit from Adaptive Cruise control and PCS with a pedestrian detection function.
Over five million Toyotas across the world now use Toyota Safety Sense; 92 per cent of new European cars are fitted with the technology. Studies in Japan reveal that in real-world traffic conditions rear end collisions are reduced by 50 per cent – and a 90 per cent decrease where Toyota Safety Sense operates in cohesion with an Intelligent Clearance Sonar (ICS).
Toyota's commitment to achieving safety within a mobile society, and believes in the importance of involving people, vehicles and the traffic environment, as well as pursuing real-world safety by learning from accidents and incorporating that knowledge in its vehicle development.
True to the company’s Kaizen philosophy of continuous improvement, Toyota is introducing the second generation Toyota Safety Sense. This comes with an improved system unit, an upgraded PCS function and new Lane Tracing Assist (LTA), while retaining the established ACC, RSA and AHB functions.
Vehicles use a single-lens camera and millimetre – wave radar with higher performance, increasing the scope of hazard detection and improving functionality. The hardware is compact and easy to install.
Between speeds of approximately 6 and 112mph, the upgraded Pre-Collision System will detect vehicles ahead and reduce the risk of hitting them from the back. The system can also detect potential collisions with pedestrians (in day and night-time driving) and cyclists (during daylight hours), with automated braking operating at relative speeds between 6 and 50mph.
The new Lane Tracing Assist (LTA) keeps the vehicle centred in its lane by assisting the driver with steering control, when operating the Adaptive Cruise Control. LTA also comes with an upgraded Lane Departure Alert which recognises the margins of straight roads, including when white line markings are not in use. If the vehicle deviates from its true lane, the system sounds a warning and provides assistance for the driver to steer the car back on the correct course.
The second generation Toyota Safety Sense will be progressively rolled out from the start of 2018, predominantly in Japan, Europe and North America.
