Bosch’s fourth-gen camera adopts Horizon Journey 6B

Behind the windshield, Bosch’s fourth-generation multifunction camera, MPC4, is bringing Chinese chips into the global automotive supply chain. According to official Bosch information, the product has secured a high-volume production program covering more than 40 vehicle models and over 200 projects in China and overseas. Its overall scale is in the tens of millions of units, with mass production scheduled to officially begin in the third quarter of 2026. Markets include China, Europe, Australia and New Zealand, Latin America, the Middle East and the Asia-Pacific region.

The camera identifies vehicles, pedestrians, lanes and traffic signs, providing perception input for driver-assistance functions such as automatic emergency braking and lane keeping. In its fourth generation, MPC4 has been upgraded to 8 million pixels and a 120-degree horizontal field of view, with a maximum detection range of 300 meters. As perception algorithms shift from an earlier focus on convolutional neural networks toward the introduction of Transformer technology, the camera, algorithms and computing platform are being upgraded together.

The most visible change is the computing platform. Bosch’s second-generation integrated front-view system used Xilinx from the United States, while the third generation switched to Japan’s Renesas. The fourth generation is the first to use a chip from a Chinese company. Horizon Robotics’ Journey 6B entered mass-produced vehicles for the first time in May 2026, powering the GAC Toyota Bozhi 3X. As of August 2026, it had covered more than 25 automakers and over 50 vehicle models, with lifetime production-designated volumes exceeding 20 million units. Bosch’s mid-range driver-assistance solution based on Journey 6M has also entered mass production.

The value of this route lies in the ability of a Tier 1 supplier’s product platform to be replicated across brands. In the past, Chinese automotive chips more often followed Chinese automakers overseas. Now, Horizon Robotics can first enter Bosch and then reach multiple countries and brands through Bosch’s deliveries. D1EV, citing official Bosch information, reported that MPC4 was developed mainly by Bosch’s China team and is being promoted globally, connecting it to Bosch’s existing customer and delivery network.

Specifically, automakers and component suppliers receive a computing, algorithm and engineering package already embedded in global programs, rather than a chip intended for a single vehicle model. At the same time, the price of front-view camera modules has fallen from 1,000–1,500 yuan several years ago to approximately 600–900 yuan, while pixel count, detection range and algorithm capabilities continue to improve. Horizon Robotics is also collaborating with Japan’s Denso, while its cooperation with Oumowei has expanded to a joint venture and intelligent-driving product development. These capabilities must still clear hurdles involving functional safety, software adaptation, vehicle validation and long-term delivery.
