TSS system in cars refers to the Toyota Safety Sense, which Toyota calls the Pre-Collision System package. The TSS system includes: The TSS system comprises the PCS (Pre-Collision Safety system), LDA (Lane Departure Alert system), AHB (Automatic High Beam system), and DRCC (Dynamic Radar Cruise Control system). Upgrades to the TSS system: It is reported that the second generation of Toyota Safety Sense (TSS) has been introduced as standard equipment in some Toyota vehicles. The updated safety package will incorporate new technologies and capabilities to enhance protection for drivers, passengers, and vehicles on the road.

Recently drove a friend's new Toyota and specifically studied this TSS system. Toyota TSS is actually the abbreviation for Toyota Safety Sense. This system integrates various active safety technologies, acting like a considerate bodyguard for your car. While driving, it can automatically monitor potential hazards; the pre-collision system can identify pedestrians and vehicles to actively apply brakes; Lane Tracing Assist keeps the vehicle centered in the lane to prevent drifting; Adaptive Cruise Control is especially practical on highways, automatically maintaining a safe distance from the vehicle ahead; it also features automatic high beams and road sign recognition. Last year, driving on the Yunnan-Tibet route, this system was particularly effective in curve warnings. The newly launched TSS 3.0 version is even more impressive, capable of identifying pedestrians and bicycles at night and detecting cross-traffic at intersections.

Last week, I accompanied a friend to a Toyota 4S store for a test drive, where the salesperson provided a detailed introduction to the TSS system. Simply put, it's Toyota's self-developed safety driving assistance package, available in two configuration combinations: basic and professional. The core feature involves dual detection using front-mounted millimeter-wave radar and cameras, which is more accurate than single-camera monitoring. The system includes five main functions: the collision warning system can identify vehicles, pedestrians, and bicycles for automatic braking; full-speed adaptive cruise control supports automatic following from 0-180km/h; lane centering assistance alerts drivers of deviations through steering wheel vibrations; automatic high beams switch when meeting oncoming vehicles; and road sign assistance can recognize speed limit signs. Version 3.0 adds overtaking safety assistance and low-light pedestrian recognition, significantly enhancing safety. Such active safety configurations are becoming increasingly common, with domestic new cars also featuring similar systems.

Last month, I just had maintenance done on my Corolla at the 4S shop, where the technician taught me how to use the TSS features. This is Toyota's exclusive safety suite, with the PCS pre-collision system being the most practical—it automatically brakes in emergencies. The LDA lane departure alert vibrates the steering wheel to warn me when I'm drowsy. The DRCC full-speed range adaptive cruise control reduces fatigue on highways, especially in traffic jams. The system automatically reads speed limit signs to alert about speeding risks. After using it, I found that the camera area on the windshield must be kept clean, as recognition performance drops in rain or snow. The new Camry's TSS 3.0 also adds emergency steering assist, and the turn signal controls are integrated on the right side of the steering wheel. The safety features have improved significantly.
